Chris,
> Please check my calculations and hopefully it will meet Paul's clarity standards:

> 180ml curds by volume + 120ml ammonia and water = 300ml solution

Yes 

> 140g washed curds x .23 = 32.2g (fairly close to the 28 gram amount of protein listed on the container)

.23 is the yield of casein from dry powdered milk, not from washed curds: 
these last are "wet casein". Assuming a .23 factor it would mean that the 
wet curds have a 1.00-0.23 = 0.77 (77%) content of water, which (if I 
remember well) has not been yet measured. 

> Oh, by the way, the most dilute formula of all the 32 formulas I have is from Enos himself, two of them, a 1% and a 1.3%, and I know one is combined with dry dichromate. Don't have enough information to see if the other one is, though, as he didn't specify.

If one is combined with dry dichromate, then you can assume that its 
concentration is double because it will not be further diluted 1:1.
