I didn't think it was that easy because, well, it's a ball and the hole in the ball has a curved edge and...ya, that. In other words, isn't it disproportional (is that a word?) because of the spherical properties of the hole? I wouldn't even begin to pretend I know how to calculate it, but I digress. If other folks are having success guessing, that's what I'll do to. I like the trickle description. That helps.
Thanx and cheers,
