Not that's it's any of my business, but man..Over a gallon of fuel, still on the test stand, and just now trying for a peak reading. I'd been flying that thing at 500 off peak about 3/4 of a gallon ago. Not that I'm putting you down for taking extreme care during the break-in, but I think you are probably very safely into the "go ahead and fly" mode.

For reference, I ususally put 2 or 3 tanks thru a YS and then fly it a few hundred off peak until it gets to where it'll hold super low idle, then fly it a couple hundred off peak.

I'm not saying you're wrong and I'm right, and it can be mesmerizing running one on the stand (they are sweet!), but in all honesty I think you could be flying that thing.
