OK well decided to go for this setup in the end:
(hands), VPIP, PFR, AfQ, steal%
3bet, foldto3bet, FlopCbet, foldtoFlopCbet
TurnCbet, foldtoTurnCbet, WTSD, W$SD
And here is how it looks on the screen, seems good now I reduced all the font sizes to 9 rather than 10.
As for convergence, I think the middle line stats take a few hundred hands and the third line stats prob take a few thousand hands cos I have 300 hands on some where the TurnCbet is still N/A (0/0).
