So,.15 hrs later that load with too much air is done.
Some 6" short (...!) red oak, 2 small red oak uglies, and a half maple cookie (6" thick, 15" dia) to get me to tonight's full reload.
70 upstairs for all this 15 hrs, currently again 31 outside.
So running a 75%(ish) load for 15 hrs does keep the window clean; only minor spots in the lower corners.
