Thanks guys. So it sounds like it's just like a regular hex3 symbol then except with the additional ability to push the bracket up 1 or 2 spots (usually one spot) just as Mickey originally stated. So we can apply Smurgerburger's equation for columns 2,4 and columns 1,5 using the stats Mickey had collected on these and posted in an earlier post (and different thread IIRC) for more accurate cost to hit analyses for the luck zones above these columns.
