Moon Phase Position Durations Inconsistent?

I am wondering why the [ mp ] tags for the Moon phase position are not consistent in duration?

The MP’s normally range gracefully between 28 and 24 hours, but near the New Moon, the durations are much shorter. MP 27 runs for a normal 25 hours but then MP 28 runs for only 12 1/2 hours, and MP 0 runs for only 14 hours, and then MP 1 jumps to 29 hours. This is from a survey from the current month of March 2021.

Jakia has a tutorial in the blogs that might help. It does not show the Full Moon as a a full day like all the other Moon phases.

If that doesn’t help you let me know and I can ask that she respond here.
