Hi Graeme,
No, you were not on drugs. If base != 0 then { if (timer - base
< 20) return 0; return timer - base -10} return timer. That will make
the subsequent comparison do what you wanted. Differences of less than
20 are unreliable because of quantization, so we return
0. If the difference was > 20, return a conservative number, the
difference -10. If the input base was 0, return the timer, the user is
just trying to read it.
Best Regards
