due to some very high pikes which have been picked up by my powermeter (50KW !) my Fenix5xplus detected a new FTP of 657 Watt or 7.08W/kg. I somehow must have exerted this wrong value. After deleting this activity, fixing the data with Fit File Repair Tool and uploading again with correct FTP of 239, the activity looks correct but if you go to 4 weeks chart it has still the 657 Watt, and it also shows this as actual value on the IOS version. I corrected the FTP setting on the Fenix as well, so my next ride will be correct again.
is there a way that I can "delete" the wrong value, or is the change picked automatically within the next 24 hours?
