Smart trainer strain does not match gradient of my ride

While on my ride today the gradient of my ride and the strain of my smart trainer were not matching up. I was riding the figure 8 loop and my trainer is the Saris H3 loop. Is this a Zwift issue? A trainer issue? Any thoughts on how to resolve this?

Hi @Michael_Rothman

Welcome to the forum.

We will need some more Info on your setup and how you pair your trainer. Is this the first time you encountered this issue?
