Except when rallying

Personally I use two things to remember:
1. Accumulate BMs normally, halve their effect
2. Don't apply the benefit twice

So in the case of assaults, a broken assault det has accumulated 8 BMs, but the effect is halved to 4.

There's probably still some situation that it doesn't work in though!
