Yes, Power On, which has always been well below Power Off, due to engine shaft limits. Of course, the N2 and Nr are married Power On, so it is the N2 that establishes the power on limit.

On each model, the typical N2 limit has been between 108 and 109 steady, and up to 112 for brief transients. This is an engine limit. The rotor has been at 115% since the beginning.
