Some time ago, maybe a year or two, somebody here posted a link to an engineering report of wind tunnel testing of scalloped vs non-scalloped wings. I wish I could find it again.
See my post about 1/2 way down the first page.

Thank you John. That's the one. Dunno how I missed that, but I sure did.
Looking at the curves on the last page of the report, it appears the scalloped wing might have a gentler stall - at least the lift curve is continuous through a larger AOA for the fabric wing, though maybe the veneer wing wasn't tested at those higher AOA'S. Anyway, that data does support the idea that the scalloping of the fabric doesn't matter a whole lot. The drag coefficient on the scalloped is a little higher at moderate angles of attack, like in climb, but not much.
