Wintertime boredom, but then I remembered that I had two stopwatches, and what could be more fun than running them against each other to see if they read the same after an hour or so? Well, they showed different times at the end. Enough to matter? YES! Using either watch, you could be more than 0.1 second off at the finish in just about any speed class.
They're both Robic SC-500, kind of the standard ORR stopwatch. So what to do about the difference? Being too technically challenged to do a GPS time comparison, I set up a highly accurate 10 MHz temperature-compensated crystal oscillator and tested each watch against that standard. One is fast and one is slow.
I sure would appreciate any of you sharing your stopwatch results if you test two against each other. Maybe I just have two not-so-good units. Of course, if I had Simon Gibbons' "big bag-o-stopwatches" I could just pick the best one. Or maybe if I put in fresh batteries.... Oh well, Meme and I use the Silkrip computer, so the watch is just for backup. But still...
Is it May yet?
