This is a really nice visualization and a fun way to play with the model. Though for any start-up that sells physical goods...gross revenue is not very useful when it comes to projecting profitability. But it's fun anyway and maybe more accurate for pure software businesses. Kudos to the author, and great that it's on github as well!
That's some really great bookending you've done. First you started with calling it "really nice" before sliding in a subtle dig by dismissing it as "fun". After that you go into why it isn't very useful. Then you devalue it again with "fun" before wrapping it with a "cheers type" salutation(one that is careful not to send a message of quality only recognition of work done) before wrapping it all up with an exclamation point. Great work!
