Desktop Dyno Accuracy?

Anybody know how accurate this program is? Like anybody really know, like put their set up on it themselves and then actually had the motor or rwhp (calculated to flywheel) dynoed and then compared them? I just ask because I threw my set up onto desktop dyno since I have all my parts now and I know exactly what is going in it. It came to almost exactly what i wanted it to put out so just curious if anybody knows anything about the accuracy of this program.

one of teh guys on nastyz28 was within 5% with his but 15% seems to be the norm (which is about the same as going to 2 different dynos in the first place)

From what I've heard it seems kinda hit and miss. In Caleb's case, didn't it say he'd have 250 HP? But yet, granted he hasn't had it dyno'd, he had a 90HP increase and says he can't really notice a difference (correct me if I'm wrong, Caleb). I would think a 90HP increase would be kinda noticable. So I dunno, I'd rather be negative and say expect it to be a high estimate, that way if you're wrong it's a happy surprise.

the big thing is it figures with everything else being optimized, also with his engine it's hard to do since the specs all have to be made up there is no set flow file and I couldn't find a spec on the heads especially

"all the power" that's uhm... 609-160... 449 more horse than I have. The difference in HP between his car and my car could be the HP for a car with more HP than a z28, that's sick.
