" If it runs good just leave it. The factory low setting was always way too fat for me....on my one DA-50. "

There will always be subtle variations engine to engine. My factory settings were at 1 3/4 Lo, and 2 for Hi. At these settings it turns a 22 x 8 Zoar at 72,000, and will idle all day at 1,500. Transition is smooth without hesitation, and I've never flown long enough to run out a 24 oz tank.
