Actually reaction time is an indication of your car and how you are launching. It has no effect what so ever on your ET or MPH, but it does indicate if you are having issues leaving the line. Take my car, if my 60' is off, chances are my reaction time suffered because I was having traction problems. I left at the same time I always do, but because of traction issues, my reaction time is slower and my 60' will be slower. If you cut on average .510-.530 and all of a sudden you start cutting .600+, the track is probably going to **** and that will show up in your ET and MPH.
