Jake B,
Not a "pro", but practically a neighbor.
Your numbers look "textbook" to me, very consistent with the standard recommendations by Texas A&M and the SRAC. You asked about growth of CNBG,. They benefit from artificial feeding, if you are inclined to do that, and will grow much faster, quicker.
The only thing I would suggest, assuming your stocking plan meets your objectives for the pond, is 1) to add Tilapia to the mix for additional forage for the LMB yet to come and 2) to consider adding a few grass carp as a preventive measure against the development of too many pond weeds.
Just about every pond in our area develops algae and weed problems at some point. The Tilapia will not only provide great forage, but also take care of algae and take the predator pressure off your young CNBG. They are one terrific tool for the pond owner/manager.
A few grass carp won't hurt anything and will help keep weeds from getting out of control....if/when weeds do get out of control, it takes lots of GC (15 to 20 per acre) and sometimes chemicals to control....and you can end up in a cycle of too many GC (almost as bad as too many weeds) or too many weeds. I try to avoid that circumstance by finding a balance of a few GC which will not eliminate all the weeds, but keep things in control.
Just one more comment...those diving swiming birds you mentioned are what we disrespectfully call water turkeys. I'm surprised you still have any at your place because they normally are gone from around here by mid-March...but they always return hungry in the fall. The management plan you have described for them sounds appropriate to me.
