Does my math look ok?

I've been planning on making Andreas Kalcker's version of CDS here:
www.brighteon.com/98951596-048d-403f-85c3-db5ff006d0ef

So far I've been able to get 114 grams of Sodium Chlorite 80% power / flake and  500ml of Hydrochloric Acid at 6.28%. In the video, he uses a 25% solution of Sodium Chlorite and a 4% solution of Hydrochloric Acid.

For the math, I tried to look up dilution math but it gets fairly complicated on chemistry sites. Then I found two old videos from Genesis II church. In one of them he shows the math for diluting the acid:
So following that I got:

to get 4% HCL:
6.28 / 4 = 1.57 parts
if 1 part of HCL = 500ml 
1 - 1.57 parts = .57
then .57 x 500ml =  285ml water
this gives 785ml of 4% HCL solution

Then I tried the same thing with the sodium chlorite, but using grams instead of mililiters. Since 1ml of water is equal to 1gr, it's easy to just convert over at the end:

to get 25% NaClO2: 80/25 =  3.2 parts
if 1 part of NaClO2 = 114gr
1 - 3.2 parts = 2.2
then 2.2 x 114 = 250.8ml water

Does this look correct? I just wanted to double check to see if I made any errors before I start to make it. Thanks!

Use the fourth converter down the page to dilute your 6.28% HCL to 4% 

Your math is correct for HCL dilution. 

Regarding "Andreas Kalcker's method" of making CDS using MMS and 4% HCL, I developed that method in 2015, 3 years before he published his book. He "borrowed" my method down to the exact recipe, without giving me credit. He is known for doing that sort of thing. I also developed the shot-glass method of making CDS in 2012, which he also showed in his video.
