I am looking at $FI30 in Odds Oracle / Poker Juice. Found that QQ33 rainbow is rather strange.

QQ33r is not in $FI30 => don't understand
QQ22r is not in $FI30 => don't understand
QQ44r is in $FI30 => sorta understand, 44 is better than 33 and there needs to be a cutoff somewhere
JJ33r is in $FI30 => don't understand why JJ is more awesome than QQ.
JJ22r is in $FI30 => even with worse 2nd pocket pair

I don't mind getting some hands wrong. I get hands wrong all the time. But maybe there is an underlying concept to be learned? What is so special about JJ better than QQ? My wild speculation is that JJ is tiny bit better as blockers for bluffing straightening board?
