Is everyone setting idle mix by adjusting to highest idle speed or vacuum reading?

after I threaded the IFR's in my metering blocks and dropped the IFR size down, I figured I would be close to the typical 1.5 turns out from seated so I set them up initially at 1.25 turns out.
It started and idled OK, kinda bumpy, kinda stinky.

after it warmed up all the way I started leaning them out, idle goes up, smooths out. keep going around the carb, a tad leaner every time. Ended up at just a touch more than a half turn out.

I was thinking wth, after all this work these should be further out, then I figured well, I dropped the IFR down but the I didn't touch the idle bleeds and they are roughly .067", pretty small.

The idle smoothed out, smells much cleaner (still smells like it has some overlap), I had close the blades to drop the idle back down...it starts up with just a touch of the key when it's warmed up...I'm just gonna worry about other things now and leave the idle screws where the motor likes them.
