OK, John, where do I start? LOL. You pumped out a few beauts. Yes, I think in your case, with the chicken example you gave, you're way too low on the total daily protein, even for the .6 gr/day, given your bodyweight is 308. However, Doc Sears bases this on your LEAN body weight. I have no idea what your % is. Lets just give an example, and ASSUME it's 30% We'll use your bodyweight as 300 to keep the example math easy. 30% of 300 lbs is 90 lbs, eaving your lean bodyweight at 210. You would then base your protein needs on that. You seem to fit into the "active" range, based on what I've seen in your posts, so we will use ,8 grams in this example. That would indicate you need 168-170 gr protein/day. Divide that number by 7 to come up with blocks required per day, which comes to 24 blocks of P / day, which means, if following the Zone, you would need 24 blocks of C and F to go with it. That sounds pretty high, but hey, your a big guy.
Okay, now, that is based on Zone recommendations. Feel free to tweak it a bit, even doc Sears recommends that. I would begin the tweaking by cutting way back on any starches for the C and concentrating on vegetables. I think you get the idea.
I hope this has cleared up a few points.
