We can read but that is like asking which is more important if you can only eat one day a week? Monday, Wednesday, or Sunday? Whichever you choose your body will still not have sufficient nutrition for sustaining life long term.
There isn't a two day window that is more advantageous as the entire cycle requires proper humidity for proper shedding. You can feel free to experiment with your own animals and report your findings to the forum. However, I imagine regardless of which two day window you choose, you will end up with a snake that has difficulty shedding properly and in a single piece. Does that answer your question sufficiently?
