On the sheet I'm looking at, they start out in the very low .4's, and start creeping upward into the mid-4's at around 5800rpm, then into the upper-4's at 6800 till the end of the pull(7200).

One thing I did notice was the run w/ the QF 1.59 annular using the 32 MABs actually made more power across the RPM range, even though it went rich at the very end, than the subsequent runs where we leaned out the MABs. In hindsight, I think a jet change might have been a better move than an air bleed change.

We did what we could in the amount of time we had. Still learned a lot, just a few more take-aways to follow up on than I probably expected.
