Your partner's BBT

There was a very small study done where couples recorded their basal body temperature (bbt) together every morning. Then scientists were able to use the partner's bbt as the control in order to better determine when the female partner ovulated. An increase in the size of the couple's temperature gap indicated ovulation.

One of the big problems in bbt is external forces. (The room being colder one day to the next, for example.) But when you take the temperature of both people in the room, you can control for this external variable. So the accuracy of your bbt could be potentially improved.

Our question to you is: Is this something you would consider doing? Would you partner go along with it? Do you think it would be useful?

Your thoughts are much appreciated!
