Because of the way ricochets work, the probability of penetration varies with incidence angle, and is closer on average to CP80 or 85 than 75. But I'm leery to give a single number, given the conditional probabilities invoved.
The values are for vertical plate at 0 range so none of them are taken from the website you mentioned, thought the site was used to as one of many sources to validate the equations used.
The derivation of the constants used is a big job the results of which we consider a bit proprietary at this point. You can find discussions of similar forumla at
http://www.tanknet.org
forum's ballistics discussion.
We are really limited in the SP architecture, the "6 slab" tank model, and the single penetration number (when penetration varied strongly with penetrator material and armor type) so "splitting hairs" on penetration is chasing "insignificant digits" in the game.
What we have shows the relativve effects of T/D and 3 dimensional angle, but the variability means that you have a +/- 10-15% range variability or penetration, and a +/- 7.5 degree variation in angle of impact in results, so tryong to pin down penetration numbers to a finer precision than that is not productive.
Combat Leader will let us tighten that to about 3-5% or so and use a more "event based" algorithm.
