  here are the results on Linux 1.2.8, XFree 3.1.1., XServer Mach64,
Pentium 100 MHz, ETH Oberon V4-0.9. I tried several times:

minTicks always 5
aveTicks always 6    (well, one time was 7)

That is 6 millisecond per one cycle, 167 cycles per second.

Max ticks varied from 12 to 695, however, 695 happened just once when 
I was transferring a large file over the net at the same time.
When I just started / stopped the loop, maxTicks was between 
12 and 34. When I started the loop and shrunk Oberon to an icon,
maxticks went up to 300. Note however that average was always 6,
all the time. 

There was only one exception: when I started the loop and then 
clicked on a PopupElement (and held down the MM for a long while)
the average Ticks went up to 26.
