Don't understand why Garmin maintain this issue , this is since the 45 series,today i did 10 kms time trial in 41:18 , before the time trial the prediction in Garmin was 43:46 and in stryd 42:29. After the time trial stryd updated my critical power and the prediction to the time i did, however Garmin prediction went to 43:57 . This is so annoying
