What if CM changes throughout the day... What do I chart?

The most fertile one of the least fertile? Or do I chart the average between the two lol?

You want to select your most fertile cervical fluid of the day. This will help the program better pinpoint your ovulation date.

^^^WSS I also make notes about the changes for my own benefit when I'm cycling through different kinds of CF.
