I don't think it will work as simple as adding "2".
Every tank has a differently curved turret, and every degree more or less actually changes the amount of armour a AP round has to pass through.

Hello
Seems to me that pz 3 tauch should have a TF value of 5 not 4 as it has a thickness of 3cm. pz 3 e with the same mantlet thickness gets a TF value of 5.
the earliest model of pz 3 converted to tauch is pz 3 d with mantlet thickness of 3cm.
Best Regards Chuck.
