Why would you ever use the "loose games" SSH chart?

[aargh57]

The loose games SSH chart says it applies when there are 6-8 players on the flop on average. Let's assume that the blinds never fold and you play 17% of your hands. That means in every pot there will be 2.17 people in it to start. That means out of the remaining 7, 3.83 people need to be in the hand. That means the VPIP % would need to be 55%. I think it's pretty safe to say that you could go quite a long time without running into a table of this type. (Also, when you start to consider blinds not playing 100% the figure gets even higher.) Am I missing something?
