In order of my perceived importance:
barometer/pressure = goooood.  I swear my ET's/MPH show noticeable improvements when we've got good pressure.
Humidity - sucks ass. takin' oxygen out of my air! Pullin numbers out of my ass here, but, seemingly 50% - 70% isn't going to change things much.
Above or below and I start seeing changes.
Air temp: now, this could start arguments, but I'm going on my empirical data. Between 75-90 degrees, not much of a difference in performance. None of my Kawasaki's seemed to drop ET when the temps had me sweating up a storm, wearing leathers in the staging lines.
Now - get below 70 degrees and I'll see the MPH improve.
......my 2 cents.
oh yeah, chipping in 2 more cents to note that an extra 1 mph gained on the big end is worth roughly .02 in ET. (with identical 1/8th ET's/mph's.)
