OK! Ive got a proof of concept.

Go here and enter your tech spec:

http://thepracticeofcode.com/techspecs/

It will remember it until the year 2032.

Once you have created your specs, you can now apply your spec to ratings. Here are some sample ratings for you to test against:

Bulkhead Rating

Movie Mudflap Rating (Note that this one is a guess as I know little of this character)

If you want to create one of these rating links, you'll see a link to do that on this page. Does that make sense? See what I mean about having to do no math?
