Is that the best lap in the race?

Hard to figure when the race leader is 21st if there is a lot of information there.

hmmmm ... 21st fastest time, over 2 mph slower.
since he led every lap, he had no one to draft / pull him down the straight ... easily worth 2 mph ...
also never saw anyone on his bumper pushing him down the straight ? what you say Jim - Mat - Todd ?

Theres still a whole lot of 5th gear left to go on that straight after the trap. I'd be more curious to know what their speeds were approaching T1 or Canada.

Compare the GT-1's with a Trap speed of 165mph and FA's with a 141mph Trap speed. GT-1's were 2.5 seconds slower a lap. Those GT-1's are bullets in a straight line. It is a graphic demonstration traps speeds are not the whole story.

I would like thank my friends Mark Bennett, Shawn Slattery, and Aaron McSpadden for running 3 wide up the front straight on lap 10.

***I think trp speeds mean next to nothing there.***

Sure, I get the picture. Let me see if I can get this correct. These trap speeds don't fit my scenario therefore they are fliers & will be discounted. [rolling on floor laughin]

***I would like thank my friends Mark Bennett, Shawn Slattery, and Aaron McSpadden for running 3 wide up the front straight on lap 10.***

I sure am happy a 1.6 didn't find that ^ hole. [duck]

Shucks, Slattery was so fast with his trap speed that the speed device wasn't quick enough to get his trap speed. [laughing]

Let me answer some of the questions that have been raised. The trap times/speeds are generated from timing loops at S/F and 120 feet past S/F. These are the loops used to capture on board transponder signals, so they are very accurate.

The times/speeds shown are the fastest for each car during the race. However, they certainly don't account for drafting, great (or not so great) exits from turn 14, etc.

There are timing loops scattered all around the track at RA. Next year, we plan to gather information from other traps and to generate sector times (a la F1).

What Drago is trying to say is: "Those of us that were there with radar guns during the test days know the real story."

Exactly. The trap is right about at the shift point from 4th to 5th and there is a lot of straight after it.

Check out the Speedcast replay of the start of the SM race and see how the two top 1.6's of Verges and Slattery faired when the green came out going up the hill. Positiion 5 and 9 [Frown]

Looks like 2 cars had less torque, or were late on the gas. Since the polesitter was a 99, you're going to get his favorite starting speed everytime. What's the old saying about horsepower vs torque? I know it won't ever happen, but I'd vote to split SM. Either that or make the 1.6 the benchmark for the class instead of the 99.

And then watch 33:30 to 34:40 of the SpeedCast race to see reality. [Smash]

Yeah, I purposely did not point that out because it was our car, but we fought that the whole race. Very frustrating, got a good run up the hill and no way to defend it.

Well Pat, I think what I meant by "reality" is that in SM, FV, SRF, FP, and a lot of the other classes I watched, you should not EXPECT to be able to hold off a car slingshotting out of your draft up the front straight, much less TWO cars slingshotting out of your draft.

The drafting 99s had to bust a move into Turn 1.

One minute of video can show anything anyone wants it to show, all I'm saying is the segment I point out is more accurate than a "start" or "restart", or showing only one side of the draft situation.
