I'm a little confused- are you supposed to chart to the 10th (97.2) or 100th (97.24) degree? I found a thermometer online that had good reviews, but it only charts to the 10th and I remember reading (online? in a book? eh, somewhere) that BBT charting needs to be to the 100th degree.
Anyone know which is correct? What do/did y'all use?
