perf(day): leave pulse to the resting heart rate in the extremes

A pulse day value is a mean over thousands of background samples, and
comparing it over two years scanned every one of them: a recent day on a
dense account took about 300 ms, two thirds of it here. Resting heart rate
stays among the compared vitals.
