ERG mode confused

So I was so confused about ERG mode in iPhone and computer. My smart trainers is Magene T300.

First time I was used computer to train. I think everything is kinda okay, sometimes my signal is weird. But that’s ant+ problem. You can see the yellow line is smooth.

In few days, I decided to use my iPhone with bluetooth to train, but you can see the picture. The yellow line just up and down.

Does anyone have this problem?
How should I fix it?

It is normal as power is never smooth.


Yeah that looks fine to me. When you see perfect intervals on other rides it’s using artificial “power smoothing.” In reality it always looks like yours.
