For the record my P20 ran out its first 25 hr service interval in 122 flights.
You'll NEVER get to 200 flights before 25 hours.
Since time on the engine is done by RPM, this just tells me that you flew your P20 at full throttle a LOT! So, you CAN get 200 flights at reduced throttle prior to the 25 hours.
