Effects, how do they work exactly?

[Hanspeter Schnitzel]

So, in the patch log it says if you have 50 effect blocks on a 100 blocks weapon system you get half the effect. So, if I connect 50 EMP blocks to 100AMC blocks (or a weapon system made out of 2x50 AMC blocks connected with eachother as slave-master system for some kind of EMP minigun) does it only convert 50% of the damage into damage for the power?

Also, how does the protection from the effects work? How much protection does one block add?
