(NEW) Garmin Forerunner 255 - GPS Running Smartwatch (International Model)

I like this watch for recording sleep and running. However, the pace calculation is almost useless. It appears to average the pace over a significant period of recent time, maybe 20 seconds. If you are running an interval workout and want to know the current pace, say over the last five seconds, then you are out of luck. When I speed up from say 8 mpm to 6 mpm for an interval, the watch does not reflect the 6 mpm pace for way too long. I had a Garmin cycling computer on my road bike for years and it allowed you to select from several periods of time over which current values were averaged, which was ideal. Garmin should add that feature to their running watches.
