Did not find any other mention of this, so I thought I'd share and ask. Interesting scenario today. My exercise this afternoon was playing some catch. HR was steady in the 120s or so. After finishing, I was still walking around a bit to an HR of about 100, cooling down it appears. I took off my Charge 3 and placed it in my pocket and walked around inside for a few minutes. Got some sticky stuff from the ball or glove on the band, so I took an alcohol wipe to it. While doing so, the screen waked up to a reading of 155-ish. Thought that was weird, so I synced with the app to find it read 186. Hopefully, that's a bad reading. Took a manual pulse a minute or two later had it at about 100-ish.
I had the occasional spike or two, though it wouldn't spike higher than 140 or so. Since it's rather occasional, I can't seem to find much consistency to lead to a definitive conclusion. The only one I can speculate is wiping down the watch with an alcohol wipe, as I often do after work late at night. During the cleaning, I would hold the tracker with two fingers, usually index and middle finger over the sensors. However it's not every day a spike in HR is recorded (as I wiped it Sat. morning at 12:15-12:30a after work) but it looks to have fell in line once or twice. Not definitively, for sure. Only other excuse for an illegitimate reading would be a measure while it's sitting in my pocket.
Does anyone have any insight to this, either capturing an largely spiked off-reading while it's in your pocket, while holding it where your index and middle fingers cover the sensors, or while cleaning your Charge 3 or similar device?
Any reason to suspect this may be a legitimate reading?
