i've been working on improving my DPS so monitoring SPL along with pace.
recently i've been seeing 17 SPL when checking on the watch between intervals which was pleasing as older activities are 19. however looking at the activity on connect after upload, these same intervals are showing 19 SPL, same as the older ones. the activity on the watch now shows the higher number too.
so it seems i haven't actually changed at all which is disapointing but the watch is misleading me by showing different numbers during the activity to what are then shown later. has anyone else seen anything similar and have an explanation for it?
