Not sure off the top of my head, but it's easy enough to test. Nin/Sam (for Utsusemi to avoid getting TP from being hit, and +15 STP), bunnies in Ronfaure. Single wield a 190 delay weapon and perform 10 attacks, you'll have either 59 or 60 TP.

If no one's checked by the time I get home I can just run out and test it.
