GM Speeding on Pit Row
.9 sec to fast on pit row. Is the gun that accurate? I mean could that be a mistake by the gun? I'm guessing that's about a blink of an eye.

0.9 km/h, not seconds, and yes it can be that accurate. As a result he messed up what could have been 3rd, but he was never challenging for the win.
Pit lane speed limit has been there for 5 years now, so plenty of time for people to get it right (and to test).

Serious question. How do you know it is that accurate. How do you know it is more accurate than the equipment on the bikes. The simple fact is you do not know.
It is impossible for any two instruments to read exactly the same, and to be calibrated the same. Impossible.
There must be a ± tolerance. Maybe there is an agreed tolerance, but if not it makes a total farce of the whole procedure.

The pit lane speed measurement is done using the same transponder on the bike (and detection loops under the road) that is used for race timing. If you accept that said transponders are accurate enough to give lap & race speeds to 3 decimal places at speeds approaching 200mph then they ought to be accurate to one decimal place for something travelling at less than 40mph. The pit lane speed measurement system is active right through Practice Week and all the teams can use the readings from it to set/adjust their pit lane speed limiters on the bikes. Remember the limiter works by controlling the engine RPM to a set value, not controlling by the bike to a set speed. Therefore the ground speed when the pit lane limiter is operative can be altered on any bike by changing the sprockets.
I'd love to see things from your perspective but unfortunately ........... I find it impossible to get my head that far up my a$$

If you need a tolerance set it in yourself by dialing in a lower speed to your bike to ensure you do not speed . While the bike is moving these races can be lost it the pit lane ! But not won !
Old enough to know better, young enough to have given it a go !

RE: GM Speeding on Pit Row
The pit lane strip is the reference point in all of this as it will measure and return the same results every time. Hence you set your system up to make sure you don't break the pit lane reference point, and test to make sure you're not breaking that measuring system.
Saying that your own system said you were doing 60 (or rather, you worked out from the rev limit that you should be doing 60), is pointless if the measuring device doesn't agree. Set the system so the measuring device agrees and you'll be fine.
I don't understand the uproar around this - 40 odd other riders managed to get it right so it can't be a bad system. If everyone was getting penalties then you would have to look at the setup.
Anyway, it only robbed Guy of a possible 3rd place - not the win.
