Question on armor advantage

[melm]

I am currently confused by the armor advantage number.

From my view,
some armored vs protected has +8 POA;
armored vs some armored has +16 POA;
armored vs protected has +25 POA;
fully armored vs armored has +50 POA;
fully armored vs protected has +100 POA;
fully armored vs some some armored has +100 POA;

It looks fine that the gap between protected and armored is 25, which is close to (8+16). But
Q1: Why fully armored has 100 POA vs protected?
Fully armored = armored + 50, armored = protected + 25, Isn't the advantage 75?

Q2: It seems some armored and protected are the same against fully armored.
Both of them has 100 POA gap between fully armored. It looks like some armored doesn't count anything.

Protected has armour value of 50, Armoured 100 and Fully Armoured 300. Armour POA is half of the armour value.

The maximum armour benefit is 50 POA for infantry and 100 POA for cavalry so with 300 armour fully armoured units get the maximum 100 POA against every unit currently in the game.

Only against infantry, against mounted the maximum is still +50.

Don’t try to look for logic in this, it was just a tweak to make cataphracts (and post-1150 AD) knights more effective against infantry. It may eventually get rationalised back to a maximum of 50 if other more logical ways are found to achieve the same effect in a future update.
