The Men's coat

I've decided to start again with my pattern as I think there might be some issues with it – following various adjustments, and so on.

I'm wondering which points on the pattern I can / should replace with measurements, and which I should leave as given i.e. scale measurements.

Also, given I established the front balance needed to be reduced with my last coat, is it a good idea to incorporate this into the new pattern, or to start again?

Thanks!
