Which soft tissue prediction is more accurate?

[father_john]

I tried using proplan cmf to plan a trimax but the soft tissue prediction from it doesnt look as good as a surgeons soft tissue prediction using dolphin. So which of these would be more accurate do you think? I do realise that the ct used for each is different but the results are still radically different.

If i were to get the proplan result i would not want to do the surgery at all. Perhaps ive done something wrong in proplan that has resulted in minimal change?
