I would also respectfully submit that a good number of people are refraining from using it because it's seen as easymode. I could be wrong on that, but I think a lot of average pilots avoid them for that reason.
It seems to me that guys that habitually fly the Brew, the Hurri C and the P38 in particular are either new, or they have put in significant time to get to know them well enough to be REALLY good with them, thus skewing the stats.
It seems to me that HTC has set up the ENY so that less skilled guys have something they can do ok in at every 'level', so that might be playing a part as well, that the Brew is the 30 ENY twisty plane of choice.
