What I found over the years on various crashed bikes is that fork tube runout numbers matter less than the old "stiction" test.
Stiction results range from pushing the forks down and they stay all the way down, (oops, oh oh hahah) to coming all the way back up to where they started. Generally, if within 1/4 to 3/8 of where you started, I'm not even going to bother taking the forks apart for a runout test. Stiction like that is fine and acceptable. Anything more and it's time for new fork tubes. Just remember that new fork seals have higher friction and they do break in after a few rides.
I don't think 20 thousandths is all that bad on skinny fork tubes. I've seen worse numbers still have good compliance and low friction. 20 thou on a supersport fork tube might be a problem though
