I did some of the firmware tunes as well as the straw method. Its been a while, but it speeds up the initial drop speed and tunes when it slows down. Improved the speed dramatically and not at the cost of over throwing. I too get some over throws on occasion with long stick powders, but very infrequently. As you state, sometimes its great and others its every 5 throws. I attribute it to humidity more than temprament. Although, it could be VOODOO at work here as well.
