| May 13, 2021 at 23:26 | comment | added | D.A.S. | the refresh rate of the LCD has no contributing error on the accuracy | |
| May 13, 2021 at 23:25 | comment | added | D.A.S. | This stopwatch does not measure in centiseconds, it measures in milliseconds | |

I've seen FSTN panels with reaction time of 50ms so it's plausible. The MSP430x4 series guide has all the scary math for driving a glass | |
