The profit chart does actually factor in a changing difficulty over time, but the output tables don't. I could see how that would be confusing. I think I'll change the second table to account for changing difficulty. Thanks for a feedback, that's super helpful!
Got it - I can see that now. Yes - I personally like the way I can see the profit values per month or grouped by difficulty jump, as on the Bitcoin Wisdom Calculator. An option to export that out data out to a spreadsheet would also be quite killer
