The looser you fly, the faster your speeds are.
That makes sense....Fred got me in a test flight at 172 on the course over a decade ago at Medford while still using Rev-up wood props (that has been a while). But it took a long time to get it wound up, and I was not using a race setting for the engine (went off very rich and clicked off laps as it leaned in with the fuel burn).
Loose.....I feel so cheap.
