well, I looked at POV help, and my best guess is it relates to the angle of
refraction.  with a diferent angle, you would strick different areas inside
your bowl, and each time you hit it creates new rays.  Well with a decreased
angle, I expect it doesn't get to an unstable number of trace levels.  But
since you want a realistic refraction of the water stay with the ior=1.33
and tweek the trace level.

I'm sure others may have a better way of explaining this if I confused you.
