With the help of a colleague, Derek Gurney, I have created an awesome tool that can be really helpful to you when you have a really difficult decision to make. Although I created the tool 40 years ago, very few people could use it without my direct help because it is a bit complicated, and it involves lots of calculations.

But now, thanks to Derek’s help, you can do it easily in our step-by-step app, and we’ll do all the calculations for you, and give you a fairly sophisticated analysis to help guide your decision as well. I think it’s safe to say that’s it’s a real eye-opener!

I don’t anything like this has ever been done before, and I think you’ll find it quite exciting as well. It takes just a little work on you’re part, and once you’ve used it once, you’ll find that it’s super easy and super helpful! You can use it as many times as you want.

This page is just a place-holder, and when the app is ready for beta testing, I’ll put the link here for you, so you can give it a try!
