Again the mid range is abnormally high and it is not justified from balance reasons. It is probably just an oversight. If one want the FF to be more accurate one can simply increase the mid accuracy then increasing the mid range to JT levels. This is a consistency issue not a balance issue.
As someone who usually argues for consistency... This point doesnt really warrant absolutely derailing the entire discussion at hand to focus on THAT was my point earlier. The accuracy issue is a means to an end, an abnormality as you say but also... Not a balance issue. The firefly needing to hit due to its low ROF is a balance issue, how the ran the numbers to allow that specificly really isn't...
