Your GPS track has red dots on it, and if you hover the mouse over them, it shows how long you stopped for. Is that a new AP feature? I don't think I've seen it before, but it looks very cool.
That's been there a long time. So, for example, you can go look at the track of one of Phil's (hard) runs and see how many times he stops, supposedly to stretch but really just because he's out of gas. :-)
Many times when I'm just riding I won't stop my watch if I'm held up at a light or something, because stopping it and starting it just seems to make things more dangerous. A careful look at the track can give the same info, roughly. But in this case I was taking sometimes long breaks to use the binoculars and camera.
I guess I've never seen it on my own tracks because I tend to keep moving...? Oh, wait, I get what you're saying, you have to stop and restart the watch for this to happen, it's not just seeing that your motion has stopped. Not quite as interesting as I had been thinking, it won't help to diagnose times when I'm standing still while orienteering, for example.
Right, have to stop and then restart the watch. Not sure what happens if you have it set on autopause, but my guess is you don't get the red dots.
Red dots = interval training :-)
I never had my mouse over a dot long enough to notice that it shows the time paused. Really cool feature.
