Apple Watch SE for Swim calibration?

Does exist some calibration for Apple Watch swim recording?

My Apple Watch doesn't track swims correctly, it counts less distance and laps than really did on the pool, I've tried use Open Water Workout for pool training and works well at first days but every day counts less distance. Today I swam 3000 meters, but my Apple Watch just count 1630 meters.

What Can I do to fix this?
