Esoteric question about how data is recorded while using powermatch

Let’s say you are using powermatch with a power meter and a smart trainer. If your power meter drops out (transmits zero even though you are pedaling) for a second will that show up in your ride data? Or will that gap simply be filled in with power data from your smart trainer?

I ask this question as I am trying to diagnose data dropouts recorded by my bike computer (killing my averages!) but not my desktop computer. I am hoping its just an issue with my bike computer.
