Not too Shabby. I decided to break it down in to 100rpm incraments for you. Then I put both in to an excel sheet to look at how far off it was accross the full span.

It was an average of 1.84% off the full RPM of your pull. It read a little higher than what you really made, but I'd say it would give anyone a very good idea of what they would run if all the info was correct and accounted for.
I can sit and play with this thing for hours.. Playing with the optimize feature is fun. Here is the programs optimized cam over your existing. Red/Light Blue are the optimized and the Green/Dark Blue is your current set up. I asked it to keep the idle vacum above 5 as that what it said your existing set up was producing.
Loss of bottom end TQ but quite a bit more up top.
