Not going to happen without a change to the database. The best BFC tracking speed is 100k/kps with a level 12 system at 4x tracking speed.
I know that you disagree with my analysis of reduced GC accuracy, but so far I haven't seen any demostration to refute it. I would really like to see one that realisticly demostrates that accepting a sub 5% chance to hit is stratigicly and tacticly effective and acceptable.
Except you failed to factor in the free 4x from being a fighter restricted BFC. Now, the fact that that doesn't restrict a player from further increasing the tracking speed may be a bug, but it's currently possible to hit the 200k mark.
In terms of PD, I'd agree with you that one would want to use larger gauss designs simply because you need PD to be as consistent as possible. If I had to choose between taking down a guaranteed four missiles or flipping a coin to see if I'd take down either eight or zero, I'd take the four in a heartbeat.
For the less critical applications of gauss weapons, however, that choice isn't as easy to make. Fighters benefit heavily from the high speeds that miniaturized gauss weapons allow, and the only weapon smaller than a fully miniaturized gauss cannon is a size three or smaller box launcher.
The thing is, statistically speaking, the gauss weapons have the same expected hit rate per HS, with the lone exception of the 5HS/85% version, which is marginally better than the others (It should be 83.33%).
