I'm curious what everyone's technique is when it comes to pressing the button at the wall. When swimming freestyle, you should touch the wall with one arm completely outstretched, with your other arm in the complete opposite position, and your body should be on it's side. When trying to hit the stop button on a watch, both arms are outstretched and your body will be flat in the water. Triathletes will say "I don't care, all my races are open water."
Yeah, if you finish a rep like the photo below, and the watch is on your left hand, how quickly and consistently are you going to get it stopped? Add that delay to the delay from the start button push to the drop-and-push for a proper sendoff streamline, and you have a fairly significant error. Add in variability between finishing on your left or right, and in the deep end or the shallow end, and that makes the data pretty corse.
Some folks here are saying +/- a fraction of a second doesn't matter. Sometimes, that's true. But when that's true, the pace clock will suffice. When you get out towards the pointy end of your personal performance potential curve, fractions of a second can start to mean a lot. When I'm doing 25's at 100 race pace, 0.20s the difference between it being a worthwhile effort or not. So i leapfrogged the wristwatch/swim-watch for something more repeatable and accurate.
