Reactive Armour in winMBT

[PN79]

Hi all
I think that ERA should work in different way than now in winSPMBT. Now ERA stop completely penetrator or do nothing against penetrator.
Some years ago there was patch for original SPMBT and there ERA did not stop penetrator completely but multiplied "steel" armor. - I think that this is way how ERA works.
So my figures:
1) for "basic" ERA
- multiply armor by 1.5 to 2 against HEAT penetrator
2] for "advanced" ERA
- multiply armor by 2 to 3 against HEAT penetrator
and by 1.25 to 1.5 against AP/Sabot penetrator

So what do you think about?
