It somewhat makes sense to me. Measuring all the time, you're susceptible to odd readings that are essentially false positives. If your device has a 1/1000 false positive rate, but you're usually only making one reading with it at a time, that's maybe acceptable. If you're making a million readings over a week because you're checking every second, than you're almost definitely going to have it show the same false positive enough that it looks real.
