Which time would you log?

MB

Ok so, I’ve usually been logging my BBT between 7:45-8:30am... this morning I first woke at 6:10 so I took my temp then, but then I kinda fell half back asleep/went comatose until 8:15 and took my temp again at that time (the thermometer read my temp faster this time)... my question is, which reading is more accurate? The one that came up at 8:15 is much more consistent with what I’ve been getting but I don’t know if that really matters. Thanks 🙂
