AT NHIS, it is a bit more work for T&S, but not that much. The folks (two of them) running the AMB systems (a dual system, so there is always a hot backup) will notice your missing transponder, and start "hitting the button" each time you pass in any case. On the fly, they go back and fudge the pass where you were missing. You still get lap times. It is a bit more work, but they are often doing it for two or three cars in some of the race groups (which seem to run Lucas electrics) already.
But, the point is moot, as the transponder system is the TIMING system (GCR 8.1.4), not the SCORING system (GCR 8.1.5), which is still done and checked by a team of people who write down your car number every time you go past the T&S building. In three part harmony. With feeling.(1) This is used to produce a lap chart that is the official SCORING of the race, and the AMB system is checked against this. If they agree (and most often they do), then the AMB system is used to print the results. If they don't agree then it is either:
A "passing" was missed for some reason.
or
There was a pass between T&S and Start on the last lap.
In either case, the AMB system results are "edited" to make the correction.
Way more that you wanted to know, but that is what happens at NHIS. Lime Rock is the same, except you don't have the problem of about 1/6th of a mile from T&S to the end of the race.
(1) Two lines from "Alice's Resturant." (The song, not the movie.) The car numbers are written in triplicate, and each list is checked against the other two. The GCR requires this for national races and recomends it for regionals.
