On pg 24, the rules talk about accuracy vs evasion. It mentions that, with a roll of 36, having +1 accuracy isn't enough to hit the target, because 26, 36, and 46 all don't hit. However!  The frame's gun is at 35. 

Does this mean that either a) +1 accuracy can't move up or down, or b) that weapons aren't damaged like internals and systems of a mech?

For reference, it looks like the frame takes up 11 through 35, since it's the LN-VIGIL
