WW II Ballistics  Tank Gun Penetration - Russia

The following is my choice of good Soviet era gun penetration data.  This is known as Certified Penetration criteria (CP).  Which means that it is based on a 80% probability of a successful penetration. A successful penetration is one where at least 75% of the shell mass (excluding windscreen) will pass through the armor.  This actually is calculated from a few test cases so some latitude has to be given. 
In some cases there are multiple values for official data. 
It looks like all Soviet block countries used this criteria but some did their own tests and calculations.
