Okay, ignore everything else. This is going to be a recipe tailored for you based 24 lb ham weight:
First, we are going to make your injection, ingredients for that will be:
Get 1 gallon of water and mix in 2 oz of your cold phosphate (mix really really well and this ingredient HAS to be first)
Use 2 lb of country brown sugar cure to the 1 gallon of water
Mix in 0.85 OUNCE of the California Ham Spice to the 1 gallon of water
Next you are going to inject to 10%:
Your ham(s) weighs 24 lb now, when you are finished injecting they should weigh 26.4 lb as they now have 2.4 lb of the solution mixed in.
Then we will make your cover brine:
Weigh your remaining solution 1 gallon of water is about 8 lb, 2 lb of cure (other additives negligible) so you have 10 lb but you injected 2.4 lb into your hams so you should have 7.6 lb of solution left. Now, take 7.6 (or whatever your left over actually weighs) and add that amount again of fresh water. This gives you your 50% strength cover brine. How you are going to cover this for 3-4 days I don't know, don't freeze it though. My suggestion would be to get something like a [Stark Butcket Liner](https://www.waltonsinc.com/stark-bucket-liners-for-marinating-brining) and use that to encapsulate the hams and the cover brine but you have to do something here. Just injecting and moving on isn't going to allow the cure to equalize in the meat and to allow the cure time to work. If you had added something like sodium erythorbate you could just hold for 24 hours but even then 3 days is really going to give you a better flavor profile
For thermal processing:
1 Hour at 120° with no smoke
2 Hours 140° and begin smoking
4 Hours at 190° until internal temperature reaches 145° Ham doesn't need to be cooked to 160° as it is a whole muscle meat. If you are making a ground and formed ham then it needs to go to 160°. I have no idea why we did 160° in our initial video, I am adding a note to that but leaving the 160° n there as well, it isn't going to hurt anything.
