Please note that I did not take the time, nor had the intention, to make this tool hyper precise; it's more for approximations. The above table is mostly rounded averages.

Truthfully, I didn't do a lot of vetting to make sure the extreme calculations came out correctly. If you find any (significant) issues with this tool, please contact me (@digipotion on Twitter/Bluesky).
