Got to go play at Xtreme Raceway Park again Sunday

We get some "no time" racers at my local 1/8 MI, they are invariably fast street racer types.
Had to laugh last Thursday. Twin turbo LS Fox body mustang, n/t. Makes a lap, VERY fast, no time on the board from his pass.
But! The board has a running record displayed in between passes showing the fastest time of the day. Right after Mr.Fox made his lap, fastest pass dropped well over a half second. I wonder if Mr Fox knows they gave his game away. (He ran 5.15, no mph).
Lots of our N/T racers run to 330, and click it off, to avoid such an oops. The 330 time will tell them what they need to know.
(I'll bet yours was 4.05-4.10?)
