I'm stealing borrowing proof from the last suggestion made 3 days ago.

polar bear-

"Brainiac price is high due to ref change. There is a current b/o of 3 on the market. Original suggestion for that ~3? So that sale was 3.55?

I just updated the lucky shot to 1.2-1.4 - that sale should be 3.2

3.2-3.6 looks like the right range"
