@svetlyak40wt Honestly, I just took 80 because it seemed reasonable. That's not a bad idea though. I was also planning on making it so you could adjust it to end whatever year you wanted it to. Havn't worked on this project in awhile but may give it an update at some point!
I've looked for something like this before. If I can give a totally subjective opinion, I'm not a huge fan of the green and red color scheme. I would definitely use this if I had more control over the theme.

I've made something similar, but on a much smaller scale (though more productive I think):
