There are some differences in the two data sets (AB vs SB Pro), and we all know that the US 120mm has been downgraded 10% or so and that some Soviet 125mm are up rated. because the russians use V80 + high hardness steel in their penetration tests something SB pro failed to take account for... in fact the 3bm32 vant and the 3bm42 mango even the DM33 are still underperforming based on the odermatt equation an old argument of mine... read to the end quote:
The Soviet standard for calculating the penetration limit of armour piercing projectiles is V80, meaning that the expected consistency of achieving full armour perforation given a certain projectile velocity must be 80%. In formulas, V80 must replace V50 (50% chance of armour perforation). For example, if a certain projectile has to penetrate 500mm of steel, then at least 80% of all projectiles of that type must achieve that standard. Also, the Soviet criteria for a full armour perforation dictates that 80% of projectile mass must be recorded on the other side of the target plate as opposed to U.S Army criteria which only requires that a hole is produced in the armour such that light can be seen from the other side. Overall, Soviet standards were not only stricter, but the steel they used for targets was sometimes of a greater hardness than NATO targets. In reality, the given penetration data may be an underrepresentation of the actual achievable penetration of these shells. source also none of those statements are related to overall weakspot probability hit... ingame its a simple flat 15% chance of hitting a weakspot... the whole argument here is stating that 15% is simply too high judging on what is already being modeled in the game and in contrast to real life
