Yeah so I plaid around with the SRM at lunch a little more. Lou, I think your might be right about it being slow in 2nd gear. It seems like down shift to mid-rpm in 2nd ~4500 gives a brief overshoot to the RPM up to 5000. It takes maybe few tenths of second to settle to 4500. This was at constant speed. under breaking with FI I'm guessing the surge with the overshoot is probably alot more noticeable.

Most of the time on the Dragon I was downshifting to 2nd at higher RPM while initiating breaking, and didn't really notice the overshoot.
