DIY 2 Part Help

I'm looking to start dosing 2 part for the first time.
I purchased a large bag of Dowflake which states 83-87% calcium.
I also purchase some Soda Ash which states 99.8% pure sodium carbonate.
I'm trying to find out what would be the correct amount to mix into a gallon of rodi.
Randy's recipe is for a slightly different concentration.

Any help would be appreciated.

It should be about 2 cups per gallon for the Dow Flake. The new product is about 10% more concentrated, and the original recipe was about 2 cups per gallon.

You might need to do a bit of rebalancing now and then, but water changes can do that for you automatically.
