Dear Forum, I just watched a video of a mid-engine rail type dragster race the quarter mile The track display showed on one run: 4.87 and 142.07 and the later run: 4.88 and 142.18. What does the 4.87 and 4.88 mean? That can't be the elapsed time of the race. 142 must be the final speed through the traps. Confused, Chuck Engles
