At this point in time, there is zero reason not to have the average wattage show on screen.
For people training, average wattage is a must. The whole point of riding with power is to see your efforts. Not just current power, but average power. You don’t need a useless leaderboard that shows people on z-power. I don’t need to see a progress bar showing me where I’m leveling up. The interface can be made much less clutter free.
