> Why would extra invocations of (random t) cause repetitive behavior?
Depends on how random your seed is.
(random t) calculates a seed based on the current time.
Unless it is done repeatedly in a very short time, that
should make a different seed each time.
Unless there is a bug in the code that initializes the seed.
