Yea, I reduced VE rpm goes up. I'm guessing but I believe backpressure for a given boost will raise with rpms. I've tried slightly different numbers in the variables, but the map still gives you a very good idea of what's going on. It may not be exact, but for $15 it's better than guessing what different turbos do. One thing it doesn't do is factor in various turbine housing sizes. If you notice I reduced boost to 16psi, and the compressor efficiency is still down around 50-55% at 6k rpm.
