Greets!

Well, I keep looking at these charts, but never seen such odd in-door ones, especially in a house that's probably built far more sturdily/massive than mine, so not sure what to make of them. For one thing, I'm surprised that a sealed Cornwall would be tuned this low or why the room has so little corner gain in any mic position.

For now then, tuning to Fs seems as good as any place to start unless you've decided to shrink the cabs much, so where are you on basic cab dims?
