You could play a weird 15/10 style where by you played random hands like 720 23s etc. V$IP measures the % of times you put money in the pot, not the actual strength of your range.
PFR similarly measures the % of times you raise preflop when you have oppertunity to do so
it doesn't have to reflect the top 15% of hands (although it tends to).
When looking at 3-bet stats you really aren't overly concerned with the exact value. You are looking for information that your opponent could be 3-betting light and then evaluating that information in light of the current situation.
Even if you think he is 3-betting light, your default play is still to fold most hands, but throw in the occasional 4 bet bluff and 4-bet value raise.
