Smart move sharing your lease worksheet. 
As you negotiate lower priced deals, keep posting your worksheet. Everything you need to know about your deal is on there.
I know the LH calculator is a little bit daunting. But there is a thorough tutorial on how to use it and WHERE you input the numbers off your worksheet.
A little tough love - your calculator skills need to improve. Based on your inputs I can tell you are unfamiliar with the calc beyond the basics. It will pay dividends if you learn to use it well. As you negotiate you can input numbers properly on the fly and gain the upper hand - he who knows to manipulate the numbers best usually wins.
Post an updated calculator and we can look at it for you. Good luck.
