&uarr; You appear to misunderstand the way armor penetration stacks multiplicatively.

40%, 25%, and 10% penetration translate to 60%, 75%, and 90% effective armor. Those latter values are what are multiplied together. 0.60.750.940.5% effective armor59.5% armor penetration.

I would recommend against bashing other contributors when you yourself use incorrect mathematics.
