Rarely could I get to 180+ without the feeling that I was going to puke, so when it occasionally spiked over 200 and I was feeling OK I knew it was just an erroneous read. If I wasn't going hard and I would have felt like barfing AND the pulse was 200+ there would be a quick stopping the bike and a finger pulse check.
