There seem to be 35% time lag for the actual ERG power changes. I.e. if my first interval in a workout is 10 minutes it will take around 13.5 minutes until the pedal power changes to the following recovery period, resulting in the “Reduce power” message during 3.5 minutes. If my interval is 30 minutes it takes around 40 minutes until the power to change to the next interval.
All this extra time accumulates so at the end of a 3h workout the actual pedal power is way, way off in time.
Also, pressing the +/- bias in the companion app sends power changes far into the future, consistent with the ~35% time lag from start of workout. I.e. if I increase to 110% 1h into the workout the power in pedals will increase ~1h20m into the workout.
I’m observing this both on custom workouts I’ve made myself in the iOS app and on workouts imported from Trainingpeaks. This worked well at some point in the past but the last couple of weeks has been a disaster, it’s just not possible to perform a decent ERG workout anymore.
