2 useful things to know beyond VPIP-PFR to help with ranges

1) do they vary starting hands by position?
2) do they like SCs/Axs/low PPs?

another trick - similar stats to you means similar range to what you would be acting that way with. Looser = wider range, tighter = narrower.

Adjust range by street. Sure, 8Ts may be in their preflop range, but they're unlikely to be re-raising this on a rainbow AK3 board...

To practice handreading you could drop to playing one or two tables for a session and watch every hand closely - start predicting ranges for all players in these hands, whether you're involved or not.
Good luck!
