I've tried this with a couple of rubs and a couple of seasoning blends, I haven't been satisfied with any of them. As others have said, a lot of the problem is the salt content. When you look at the nutritional label, the serving size is usually 1/4 tsp, or 1 gram, that usually equates to somewhere between 9% - 12% of the recommended daily allowance of sodium, depending on which rub or seasoning blend you're using. I found that it starts to get too salty, for me, at about 14 grams per pound of meat, but it isn't seasoned enough, for me, at that point. There are some low sodium choices out there that I will probably get around to trying eventually, since I'll be able to increase the amount used. Good luck on that spreadsheet, zwiller. There's no way I could pull it off, but I'd love to have it. One other thing to be aware of is that many of these things also contain a tederizing agent that will definitely affect the consistency of your sausage in a negative way, in my opinion. Good luck!
