However when light gates are used they are often connected to millisecond timers and this is what I have assumed to be true in this case. It would be hard to have the quoted time as the average of the time if it was a centisecond timer which was being used? | |
| Sep 5, 2017 at 11:49 | comment | added | sammy gerbil | As the timing device itself seems to be of a high precision and probably of a reasonable accuracy... This is an unjustified assumption. The OP has not provided any description of the time measurement. The average time is quoted without any standard error. It may have been given a spurious level of accuracy. | |
