Example: -- I am Twi'lek (bad choice for a rifleman!) and my mind bars are migrated to max 1100 500 500. -- I eat muon gold and they quickly become 1600 1000 1000. -- lets say 10 minutes later, after some heaving shooting, and immediately before the downer, my main mind bar value is 400/1600 (i.e., my mind bar is at about 25% full) -- BOOM! muon downer hits -- my mind bar Max value becomes 1/2 its normal 1100, so dips to 550 -- my mind bar Actual value becomes (current value - 500), so 400 - 500 = -100 -- I am INCAPPED! -- I lie around and/or sit quietly for 3 minutes, and they return to max of 1100/500/500.
