Phil, thanks for that analogy. But I'm a bit confused. If the ball is moving in the direction of 3 o'clock, wouldn't the separation point be 5 seconds BEFORE midnight? Doesn't the air cling to the ball for a short distance past maximum circumference?

Also, since water is 800 times as dense as air, wouldn't the Reynolds numbers for the bowling ball and golf ball be very different? Or was this compensated for in the bowling ball analysis?

Thanks.
