Hi Alex

I don't understand the point of "wait 0..." When I comment out the line, the
program runs 300 revolutions in 2300 millisecs on my system (this is an
average of 10 trials, using the default settings as in the stack you
uploaded). With the line back in at "wait 0", it takes 1962 ms on average.
This seems a little odd.

But the weird thing is that the second, faster version with "wait 0..."
actually runs far more slowly - the millisecs are lying to me! Using a
stopwatch (I know :-)) I reckon it takes about 10 times as long as it
reports - around 19 seconds in real time, while the commented-out version is
running in just about the time that the millisecs report.

I have looked hard at the code, and at the documentation of "wait". Now my
brain hurts. What am I missing?

regards
John
