HI all - I have a forerunner 945. It has never recorded by 50metre lap swimming distance correctly, always overstating it. I swam in a squad this morning and swam 2.3km and it recorded 3km. Looks like I'm an Olympian but .... Any help please. After reading some of the other posts, I've reset the pool swimming to defaults. After selecting this, and moving to YES it doesn't give any indication that it has actually updated.
