swimsense missed 250 - 300 yds worth of backstroke, free combined.
71 % free 21% br, 8% back of recorded strokes. See swimsense log for more details. This felt great.
Shoulder a lot better than last time. A couple rounds of 100 yd IM, but swimsense never detects my fly.
So I think I did a total of 50-75 yards of fly.
