Let me also ask whether the factor matches what you would see in a
game. For instance, if we calculate a player's touches per minute to
be 2 per minute, would that mean that, if he played 35 minutes, he
would touch the ball, on average, 70 distinct times in those 35
minutes?

I ask because the formula seems to not include rebounds. Obviously,
guys touch the ball when they get rebounds. If X and Y are team and
year specific, then it is possible to have a couple guys with very
different rebounding totals with similar possession factors. For
instance, Jon Barry and Ben Wallace aren't terribly different in the
main factors you list. Wallace has lower totals in all but FTA. But
he had 800 more rebounds than Barry. How do these guys stack up?

What was the original goal of the stat? Is it better to say that it
is an estimate of touches on the offensive end?
