Strong evidence of a structured four-phase system in the Voynich Manuscript

[RadioFM]

EDIT: Your deterministic mapping from Lunar_Angle to Phase in generate_lunar_angles_seed.py makes the Lunar_Angle a trivial predictor to Phase - is Lunar_Angle a feature fed into your ML model?


Regardless of the previous EDIT, would you mind answering these questions?

1. The sweet spot is 4 phases then - any other number just doesn't yield such good results?
   
2. How's the performance with a single decision tree instead of random forest? Unless I'm doing something wrong, scores seem to be good
   
3. You're splitting the data 75% train vs 25% test on the shuffle/ablation/etc validation step w/ the same seed as you did back on training, correct?
