T-72M1 question

[Companion]

I thought T-72M1s are roughly the same with T-72A(1)s without the missile launcher gadget.

But on many OOBs (in SPMBT) protection level of T-72M1 is better by some margin even compared to T-72B1 and T-80B of Soviet/Russia OOB.

And although protection value of units named "T-72M1" are identical in most OOBs, in some OOBs, (Iran, Czech, Finland) values differ.

Is this something neglected or does the CAMO team have a good reason to be convinced of current values?


Another question:

I am trying to apply this information in my SPMBT OOBs
(a new T-72M1 damage model for SB Pro. values are non-LOS values):

What would be the reasonable value to assign? (For the T-72M1 turret frontal protection)
