Big dip

New to bbt and wondering if it’s more important to temp at the same time every morning or when I’ve been asleep the longest? This morning I took my temp a couple hours earlier than I usually would, because it was my longest stretch of sleep and it was 96.58. I took it again at 6:30 (around the time I got up) and it was 97.37 but I hadn’t been asleep more than a couple hours since the last time I got up to pee.

Which temp is more accurate???
