This does not work in backtests:
FINwithRE: pref(if(trbc2.s=40!60,1,0),if(sector.s=7,1,if(incd.s=933,1,0)))

Yep thanks for the reminder. Back when that happened I looked at your post, excellent treatment of that transition.
Not remembering why I stuck with the above formulation.
I think it didn't materially affect the backtests, and it works the same for current picks.

I'll re-check, since I make a lot of mistakes and misremember things.
