My Apple Watch was reporting a certain distance walked on an indoor walk. Suddenly after a couple of months, the distance walked dropped by about 30%--step count and time remained the same. Then just as suddenly about 3 weeks later, the distance went back up!!!
I don't expect perfect accuracy, but do expect precision (the same answer day-to-day).
What is going on and how can I fix it??

Your watch arm has to move freely, since this movement is used to calculate your distance indoor, due to the missing GPS distance measurement.
Calibrating your watch can also help to get stable results:
