How much time can I subtract for a 20mph head wind?!

[Obsessed]

Did my first 1/4 mi passes and could only do a couple 10.7s. There was a major head wind. Should I not be so embarrassed? Maybe they were more like 10.1, 10.2 runs!..

Also, my times got slower as the day went on and I wonder, how noticeable is it if your clutch starts to fail?

What were your 60' times? My first 4 passes on my busa after dragging a stock wheelbase R1 were slower than the R1. A headwind will hurt, but not as much as lack of experience.

If you have slips from your runs compare a given distance to see if your mph is consistant + check out you 60' times...to some degree you can take your best front half and your best back half times and add them up to set a possible target time
