When using power match, does your trainer fail to achieve target power?
I have raised a ticket for this, but want to see if its a problem that is experienced by anyone else as the support team is confused too.

I am using power match, riding in various gear combos to see if wheel speed is the issue but the problems remain. These are them…
When riding below 200w, power match works great. However once I start over unders, the power never reaches the prescribed target. The ‘under’ is slightly off, but the ‘overs’ are never on target. Say its 216w target for the ‘over’, the PM only registers 205.
If I increase the intensity of the workout, so the ‘over’ target is at 280w, the PM will only register 260w. Same case with VO2 efforts. This is with power match enabled. In resistance mode, no issue as I can just pedal more!
I have used PID loops, so understand what should be going on. If the PM is registering 205w, TR should be instructing the trainer to increase the resistance until PM matches the set point (target power).
I know the trainer can achieve the power because it does when I increase intensity.
This is an Over Under interval. At the start power rises nicely, then drops off, takes 45 secs to stabilise. First ‘Over’, the power does not meet target. Second ‘Over’ barely makes it. I raised the last ‘over’ by increasing the intensity. Trainer didn’t respond! Last messy part was in resistance mode to see if trainer can go higher.
Even looking at the yellow power trace, it fluctuates above and below the target line on the Unders. On the overs, it barely makes it above the target.
