Hi Chris,
This looks like it could be a good resource for some quick calculations. I haven't had time to check your math, but it seems reasonable off the top of my head.

If there was one thing to criticize it is your presentation. There were some things you did which confused me a little bit. Maybe it is because I read into things too much due to my familiarity with this material. Some of your terminology is also a little confusing. Nothing that some massaging can't fix.

Overall good job! The best part about this sheet for me, is the lessons that YOU must have learned while creating it. It takes a certain familiarity with the math behind these concepts to create something like this. Kudos to you for taking the time, it will certainly serve you well in the future. I hope you continue to evolve & improve your sheets, because as we all know, design IS an iterative process.

Kudos!
