I think you certainly have a point that VP$IP points to a range. I think though we need to also adopt the PFR stat to thsi to better undertand a players range.
Someone with a VPIP of ~20% and a pfr of less than 6 is basically on raising big pps and undominated aces/overcards. So in that case i think there is a case to put these people on cards pre/post flop. Of course a lot more players have PFR of 7+ more so in 6max, where i argue players have PFR of 12+. That doesnt denote a range so well as these players can be mixing any two into the mix here as noted above. Therefore i think you make a sensible point, that VPIP and PFR denote a range but i think PFR denotes a range better than VPIP does.
