+1 to what everybody wrote about creating different cc1 curves for each section. It sounds much more alive.
This question hasn't been answered as far as I can see. It's important that you have a clear idea about the dynamics in your piece. And not just the macro dynamics like: it's piano for the first 12 bars, then forte for four, then piano again for another twelve. No, you need to think in musical phrases. Then it will get much clearer and easier to perform cc curves that are matching musically. For example, your piece might start in piano, with a slight crescendo for the first two bars, and then a diminuendo on the ending of the phrase in bar four. If you know this before recording your instruments, the cc curves for the different sections will come out similar and will need only small adjustments after recording.
Years back I have posted a comparison between using the same cc1 data for all strings sections, vs recording individual cc1 data for each section:
Have you ever heard of some arcane device called ‘part writing’? Ever wondered if it could help you improve your writing? If the answer to the second question is no then congratulations. You can save yourself the hassle of reading through this and just have a quick glance at the fancy pictures...

It's not a one on one comparison because the ensemble version doesn't have proper part-writing. But it gives an idea of the differences it can make.
