Obviously,
Dont just do the tone & leave the face flat, you gotta adjust the face to fit, you can stretch and move the scan around firstly to get the best position, then look at always starting with the nose first, once thats in place again from the side then front the rest should go smooth, usually I start with nose first then mouth,
My bad, i didn't read what you said properly. Thought you were saying you didn't need to build the face but after reading it again i get what you meant. I don't blame you for not posting the formula for each one either, it would take forever.
Just trying to help out the people who don't know how to do it mate.
