I made a demonstration using Wolfram Mathematica which allows you to input your tire diameter, FD, and gear sizes to see what MPH you're going for what RPM your turning. It's nothing spectacular, but you can access it anywhere you have the software on your computer. There's a ton of good stuff on there you can look at too.

Here's an example of what it could look like.

Here is the link to the page.

If anyone has any suggestions for changes or updates please let me know.

You're right, that's pretty funny now that you mention it.

This one sure isn't anything fancy, but I'm using the bottom end of the functionality of this program to say the least.

His new one didn't have a graph. I really liked the old one though so I did this.

I was joking about APP but as long as you have excel the old one is still available. You can get away with some editing of the 2nd data page but there are some errors in the spreadsheet for the transmissions at the bottom.

That's cool. I really made this one so that I could always have access to it when ever I had the internet. I'm also trying to hone my skills so that I can make a total timing spreadsheet.
