Extended engine motorings:
B737NG
• Starter usage is limited to 15 minutes for the first two extended
engine motorings. A minimum of 2 minutes is needed between
each attempt.
• For the third and subsequent extended engine motorings, starter
usage is limited to 5 minutes. A minimum of 10 minutes is
needed between each attempt.
Can anyone explain

Starter cycle duty times is due to heat issues. If you keep going past the limits (not sure why you need a 10 minute motor?) you stand a good risk of the starter having a catastrophic failure.

OVER ENGINEERED?
don't see any reason to motor for 15 minutes. the most is probably for say 5 min in the event of a tail pipe fire. haven't the faintest idea why one would require15 min twice and another 10 min on top !
