Is there a way to configure the watch to more accurately record treadmill running?

I’ve used the watch a couple of times while on the treadmill at the gym, and the distance the watch thinks I’ve run is way off what the treadmills think. I’m inclined to believe the treadmill output based on all it having to do is measure the speed it’s spinning, and not best-guessing it like the watch would have to. However I need to run 5.5k on the treadmill for the watch to think I’ve run 5k, which is a huge variance for a 5k. I’ve tested this on different treadmills with the same resulting variance.

I’m sure the Fitbit I had years ago allowed me to configure stride length to get a more accurate measurement, but I can’t find anything like that on the watch. Can anything be done to improve it?
