I am very interested in getting one myself.
Perhaps in the future this forum can provide a place for all the compatible data log system users to share lap data.
Theoretical fast lap time.
Is this lap time possibly not attainable?
On occasion “best” section times may have occurred to the detriment of either or both the preceding and/or following sections.
With this data should a racer first validate the section times in a theoretical fast lap before using it as a meaningful goal?
I predict Jim will get his 1:28 in 06!

Jim will get his 28 next week.
I was on hoosiers w/ 10 cycles and a bad rear bearing. The bearing is fixed and I've got stickers to use w/ ACRA.
The theoretical fast lap time was based on 12 laps, of which 4 were in the :29's and 6 were in the 30:'s. Lap 1 and 12 were throwaways since they were warmup and cool down laps.
I think the theoretical fast time IS attainable. What may occur is that when session lap times are closer (running more consistantly), the TFL will be closer to what the fastest lap time is. In general, I don't do susp. or tire pressure changes. W/ this I feel the G2 will be able to show if setup changes affect lap times.
BTW...there has been some discussion as to how accurate GPS is at plotting COG (course over ground) The G2 had my fastest lap @ 1:29.120...timing and scoring for the event (AMB) had it @ 1:29.117. That is about a 1 ft. difference. Close enough for me.

FWIW, rumor has it (shhhh --we must keep this a secret) that Jim did 1:27.4 at Willow this week!!! But, don't say I told you!!
WOW! A 1:27.4? Jim, you're my new hero! That's faster than Kevin Roush's V3 track record at WSIR. Or is your car in V2 now with the 3.2 and other improvements?JHPGT3 wrote: FWIW, rumor has it (shhhh --we must keep this a secret) that Jim did 1:27.4 at Willow this week!!! But, don't say I told you!!
No...it's a V1 car now. Believe me...I'm no Kevin Roush, not by a long shot. I'm running 4 sec a lap behind the mid-pack cup cars, so in a sprint race I usually don't get lapped.

Just for the record, the timer had nothing to do with Jim's improved results this time. Maybe next time.
He hadn't used it to analyze anything prior to doing his 1:27s. He was just using the display in the cockpit, which he really likes.
Why don't we just follow him around the track, do some 1:27s and send the other timers back!!!
