good
my contact with statistics instruments ended few years ago when i got promoted from analyst position...
but remember as it was yesterday from my university that if sb want to run short research about sth it is advisable to use it if number of runs is < 30 and as long as it is close to that value t-student probability distribution should be used to describe population.
normal distribution is not valid unless you want to run >30 or so :-)
certainly there will be sb here with math degree who can take care with results


BTW Student was a nickname from Gosset -

Man, I must be doing something wrong. I've sent six BB's and assorted CA's against targets on Honshu that recon says has almost 100 a/c and 70+ LCU's and there were less than 10 a/c destroyed and maybe a few hundred casualties. NO DAMAGE to port or airfield. The only tac-nuke I've had was the first bombardment of Truk. On all turns after (I'm talking for weeks after) there was "realistic" damage: a few a/c and some inf and guns. Doesn't matter how many BB's I put in the TF.


Any chance you were using the same TF, IOW, the same commander?

I'm glad you think it's such a fabulous idea sneer. As you pointed out, objectivity and repetition are crucial to a tests validity. Since I'm going to create the scenario (no small feat if you've ever actually created a scenario), I'm sure you'd like to volunteer to run the first round of twenty tests.

He're what I'll do.

Create a scenario with 4 bases. I might be able to use the Saipan scenario as a starting point but if the terrain types don't match Akyab, I'll just use Burma. No no biggie. But these four bases will have the same terrain type as Akayab (once again, we're trying to limit the amount of variables to be able to focus the test, but I'm sure you knew that!).

I can name the bases appropirately, so that when the combat comes up, it'll refect which base (and test) is being run.

Base #1 = A9 = Allied base with fort Level 9
Base #2 = A0 = Allied base with fort Level 0
Base #3 = J9
Base #4 = J0

Setting them up in this way will (hopfully) allow us to test the following:
1. Do fort levels have any reducing effect on bombardments? (I believe not, but that's for you to prove!).
2. Is there any bias for Japan or Allies in the bombardment routines? (Again, I believe nukes are -not- biased toward either side in execution).
3. Establish if available ops points (thru range) has any effect on the damage inflicted.
4. Attempt to establish a baseline thru repetition, and see if we can obvserve what triggers the massive "nuke" result. We can do this by...

The IJN bombardment TFs will each have
CL Sendai
CL Kuma
CA Suzuya
CA Atago
CA Myoko
BB Kongo
BB Kirishima

(matches the conditions of the bombardment mentioned previously, we're trying to duplicate the result after all).

There will be 10 IJN task forces, with the above ships listed in each. Set to bombard each of the F(0) and F(9) bases, there will be 5 TFs, one at range 1, one at range 2, and so forth, out to range 5.

I'll change the names of each ship so that it looks like :

CL Sendai - F0 - R1
CL Kuma - F0 - R1
CA Suzuya - F0 - R1
CA Atago - F0 - R1
CA Myoko - F0 - R1
BB Kongo - F0 - R1
BB Kirishima - F0 - R1

CL Sendai - F0 - R2
CL Kuma - F0 - R2
CA Suzuya - F0 - R2
CA Atago - F0 - R2
CA Myoko - F0 - R2
BB Kongo - F0 - R2
BB Kirishima - F0 - R2

Reflecting the base to bombardded, and the range that the group came from. What you'd end up seeing in the combat report is something like

---

Naval bombardment of A9


Allied aircraft
no flights


Allied aircraft losses
P-40E Warhawk: 17 destroyed
T.IVa: 4 destroyed
Swordfish: 3 destroyed
Spitfire Vb: 10 destroyed
Catalina I: 2 destroyed
Wirraway: 1 destroyed
Hurricane II: 1 destroyed

Japanese Ships
CL Sendai - F0 - R1
CL Kuma - F0 - R1
CA Suzuya - F0 - R1
CA Atago - F0 - R1
CA Myoko - F0 - R1
BB Kongo - F0 - R1
BB Kirishima - F0 - R1



Allied ground losses:
1800 casualties reported
Guns lost 29
Vehicles lost 7

Airbase hits 15
Airbase supply hits 18
Runway hits 142

---

See how that makes the job of analysis easier? I just knew you'd think it was pretty slick. But it's the communtity that will do the "analysis", not you or I, because objectivity rules!

Only one bombardment at each of the four bases per turn (obvioulsy, or you'd stack the damage).

Basically, I'll set up similar TFs for the Brits to bombard the Japanese bases. I was thinking of putting a typical, and relatively like-gunned, group together:

CL Dragon - F0 - R2
CL Durban - F0 - R2
CA Norfolk - F0 - R2
CA Dorsetshire - F0 - R2
CA Sussex - F0 - R2
BB Resolution - F0 - R2
BB Ramilles - F0 - R2

But you can pick the Allied ships, if you want, no big deal to me.

For each turn, there will be four bombardments, on against each base. You'll just select a TF from range 1, and send it to its destination, and likewise for the other three (4x tests at once). The combat results themselves will display all the relevent information for each test case.

You run the test 20x for range 1. 20x for range 2, and so forth until 20x for range 5. I completely agree with you, 20 tests will give us an excellent sampling!

===

And of course, anyone who doubts -your- obectivity (I have complete faith in you by the way), can run the tests themselves (I'll post the scenario for all to dowload). If somebody thinks your testing is questionable, all you have to do is tell 'em to dowload the test scenario, and run it for themselves.

It'll be "Put up, or shut up" time .

=

Some things about the above bombardment that I can't include in the tests:
The minefield. In game, it's fairly large, but you can't place mines with the editor. So we'll have to do without.

There is a PT boat squadron with 4 PTs that triggered a combat before the bombardment. I can place them if you want, but frnakly I don't think it's absolutely nessary (since they obviously didn't mitigate the bombardment at all anyway). You call if you want them placed or not).

===

More to come, feedback early on our test plan is welcome. Natureally, sneer has to sign off on the test plan before I code the thing, but community input (objectivity and relevence) is requested.

Toddler needs breakfast, but I'll check back in shortly...

how about randomiser - as far as i know it is fixed within save file so result may go same - similar ????

The other variable that should be kept as consistant as possible is TF commander. Can you identify opposing leaders whose command characteristics are closely alike?

I have experimented against the AI on the effect of changing commanders on naval battles and I convinced myself that differences in commanders make a difference in battle performance. (I've seen the same thing for air commanders and land commanders.)

And no, I have no intention of doing any sort of statistical analaysis - I'll leave it to you professionals...

I'd say this is the expection.

My experience with IJN BBs on a bombardment mission is you are luck to do any damage. Once in a great while you get a good hit in but the norm seems to just dink the shore.

Worr, out

Feinder, when you get the test senario built, sent it and instructions and I will run a number of tests for you. It it time to run the tests and publish the results. without controlled tests arguement is worthless. Let's start with the facts and then analize whether the game is right or not.

"Analize"? Does that involve some sort of probe?

Randomizer - Actually, what you'll be doing is loading it as a new scenario as head-to-head (that way you can view damage to both sides).  Then issue the orders for each of the 4x TFs to bombard.  Check the damage.  Then fire it up again.  You can't run it successively, because the damage to the bases will need to be reset.  But I've done fairly extensive testing (on other things), and it'll create the new random seed with each restart.  Won't be a problem.

TF commanders - good point.  I'll set them all to the same stats.  I'll ask Kurt will send me the name of the TF commander in his group, and I'll make clones of him for each TF.

I think you need to factor in the detection level of the base, but I'm not sure if this can be recreated in a test environment...

Don't go near the drunk fat bunny waving the chainsaw!    It can't end well.

I need one of those hand slaps forhead smilies.....


Three relevent points were:

1) Yes Virginia......Fortifications do reduce casualties/

2) Yes Virginia......Recon (i.e. Detection Level) is critical. It doubles bombardment effectiveness.

3) Yes Virginia.....there is an Easter Bunny....and he's kicking ass!
