PM5, LiveRowing app or iPhone f'ed up. Probably PM5 since app recorded the 2,044 posted listed two above but gave it the same time as the 4000m warm-up above (but no evidence of the 2,044 in the PM5's memory). Had set app to 2000m for all-out attempt. Crossed the 2000m (counting up - suggesting the PM5 wasn't talking to the app) mark averaging 1:42.2/500m. Rounded up to 1:42.3 = 6:49.2 total time. Deleted 2000m warm-down from this list so the total daily meters (~8000) is accurate. Possible I was below 6:49. Arg.
