Given your recent change of direction to standalone, I was wondering whether its possible to have a real time W Capacity Speed Dial, showing how much left until exhaustion during an activity. I know this moves intervals into a slightly different direction from static analysis, but its immensely useful for workouts and online races. It would mean pairing with an Ant+/Bluetooth Power Meter or Smart Trainer to an active Capacity manager (using your Morton’s 3 Parameter CP, eg. W’ 9191 J.
I do think that W is very underplayed here on Intervals. I certainly use it to determine breakthroughs of capacity. (0 or -ve values)
