I know I'm not an expert but from your lab report, I would say just make your mounds and go. Your old soil looks good-- you didn't get the N test, and you said they're yellowing, so clearly it's missing a little N, but you're adding fresh coots on top, which as you can see from my results, is really high in N, so they'll be fine, and if they start yellowing later in the season, feed them some N. It was also a little low in K, which the fresh coots has a SHITLOAD of, so you're fine there, too. And as for the Na, I'm sure your fresh mix has enough there, too. Mine was very high in Na. I think your old mix was also a little deficient in micros, but you're spraying micros, right? Because you should be anyway because even the fresh coots has a shitload of K so it locks out micros.. so you're fine.
So in my amateur but somewhat informed estimation, you should just cut your losses and make your mounds.
"sunk-cost fallacy. When one makes a hopeless investment, one sometimes reasons: I can't stop now, otherwise what I've invested so far will be lost. This is true, of course, but irrelevant to whether one should continue to invest in the project."
edit: does leadsled know that your lab report is for old coots mix? I'm just wondering if he's thinking that it's new stuff, and like milkyjoe said, is worried that the oyster shell Ca might give a false CEC value which would throw off all the cation nutrient target values. I don't think you would have to worry about that with old soil since the oyster shell Ca is free? Just a guess. Take that with a teaspoon of salt.
