This is my first working solution with some minor tweaks. Shooting for 5 seemed like the obvious choice, and while there were some road bumps, working backward meant I had this knocked out in a few hours. I'm honestly not sure if sub-5 is possible, I'd imagine so but I'd guess the amount of time needed to get a working solution gets absurd if you don't have a full-access bonder. Good job to anyone who figured out 4, and if 3 is by some miracle possible, an extra good job to you!

This is a phenomenal metric, I loved playing around with it. If people chose to shot for sub 5 I can imagine it being more painful, but this was incredibly enjoyable for me.

Made this with no external tools, just good ol fashion dragging a copy of the instructions to the end :)
