I don't really understand why such a formula would even be useful. What does it matter if a girl has 90% interest or 75% interest? As far as I'm concerened, interest is a true or false proposition. If she has interest, you should pursue her. If she has no interest, there is usually very little you can do to change that.
I know it's tempting to try and quantify interest so we can know if a girl "kinda likes me" or "really likes me" but in the end it doesn't matter. You're either dateable or undateable and that's all it comes down to.
