I'm switched from the older 735 XT - which I love.
Coming to the 245 Music I noticed that my HR average and pace are always off.
On my old watch, when I'll do a short warm up. I have my data screens set to display avg HR and avg lap pace. Warming up seems ok I guess but once I go into faster splits my displayed avg barely drops. In comparison, my 735 XT always seemed to keep up with paces. My 735 XT pace display avg pace eventually catches up.
In addition, my avg HR readings barely move the dial when I increase paces. However, when I switch it to HR zone monitoring - it seems somewhat accurate.
Am I the only one experiencing this? I'm tempted to go back to my 735 XT, especially during races. I need more accurate data logging.
