Uh ... what magic 76 degree closing point? All of these computed/assumed closing angles vary from cam to cam, regardless of program.
I just Googled 'Pipemax DCR'; there are tons of threads questioning the DCR results. What I am trying to explain is that the program is computing DCR in a way that is not the 'normal' way; it gives much higher results than what the vast, vast majority of people refer to as DCR , and that is because it computes quite a different angle. If it's computing something that does not relate to what most people use, then it is pretty useless.
BTW, DCR is a simple computed value. (Well, simple if everyone uses the same angle reference!) All the thoughts of how it varies with RPM, VE and such, is more commonly referred to as 'effective CR'. That term has been around since at least the 60's.
