Just went 10.673 on a single try in testing, on iOS. Much thanks to RJ for this, as it's 98% his work. This is WAY sub-optimal, as this is a 1/4 tune that adds 6th for the 1/2.

Can improve a bit if you stretch fourth a little and change 5th to the 6th gear numbers. 5 gears is plenty for 1/2 on this bike.
Just experimented. Put 5th at .924, and I went 10.666 @ 242mph, 1.34 short. More to gain (fourth was too short, for starters), but that'll get you into the 10.6's anyhow.
Again, thanks to RJ for working this one out. I forget the original setup, but it was blowing the tire away for me, and I had to lengthen a gear or two to keep the tire stuck down. For 1/4, the listed tune can manage 6.846's, but it's unusual. 6.85's are very, very doable though.
