Powermatch but TR & Wahoo Bolt have different numbers?

How is it that I can do a ramp test using powermatch, but TR through my Kickr Core have slightly different numbers than what’s recorded on my Wahoo Bolt? It’s only a couple watts but I don’t understand how they could be different, is it because they are pulling power samples at different times @Nate_Pearson? Below is the final minute of the test?


Final 3 minutes:

Yah, it’s probably when we pull stuff. We sample at once per second.
