Hi everyone, my multisport cardio seems to count around 50% more lengths in the pool than I actually do. I have no idea why, it lays about 4/5 lengths before it starts going a bit crazy. I just don't understand why. It's weird because my wife has the same watch and at worse hers is only ever 1 or 2 lengths out. It makes switching off impossible as I constantly have to count myself and totally mucks up my records on the app, can't see if I'm getting faster or anything.
Any thoughts welcome. I have checked and it's set to metres and all that jazz.
