Does my math look ok?

Never heard of mixing the dry ingredients without diluting before. Was that only for testing purposes?

I am surprised your water has TDS total disolved solids of 47. Our bore water where I live comes from the Great Artesian Basin at a depth around 600 meters or 650 yards. TDS of 19 . Cant stand the taste when it is warm, Being cold helps. Making tea tastes like someone was sick in it. Drinking coffee dont notice a lot of difference. Drinkable. But in our water  TDS the % of Calcium is high. When the lawn gets watered the spray settling on brickwork leaves white powder. Tested 15 years ago by the experts and the report came back, unfit for human consumption. 
So I wonder with all those minerals in your water is okay for making CDS or adding it to MMS as I thought it is best to use distilled water and now the thinking is Raising the alkalinity of the water to be used. Our bore water is alkaline . Ph...i dont know. I drink daily Rain water drawn through a1 filter but rain water ph is around Ph 5-6.5 Pure water around 7 is about neautral, Blood Ph is 7.465 if I remember correctly. Too much Calcium can create a lot of problems, kidney, heart, blood etc.
I thought too many mineral in water would not make good MMS . Dont know, maybe someone can enlighten me. Always willing to learn. 
Lastly any idea how much triple filtering would bring the TDS down to maybe? Buying distilled water can be a  bit expensive after a while.

I have recently uploaded a calculator that allows you to use any strength of solution. Why pre-dilute the NaClO₂ or HCl when all that does is introduce more water into the reaction chamber, which will retain ClO₂ in solution in proportion to the water present? Simply plug in the concentration of your solutions, set the volume and concentration of the desired CDS and it will tell you how much of each component to use. You could even calculate the reaction using undissolved NaClO₂ although I do not know how wise that would be, particularly with concentrated acid.

Woofy, the triple-filtered well water I process has a TDS of zero. First filter is a Berkey followed by two ZERO filters. That is the water I usually use to make CDS, etc. 

I only tried using unfiltered well water once, to see the results.

So my components to make CDS finally arrived from Germany via The Netherlands reseller. Link  here

I bought a two compartment Pyrex Benito box to use as my reactor.I followed the instructions from  this  video.
I used Glaceau Smartwater Alkaline 9+ph as my water source and added 400 ml (fridge chilled first) to the bigger compartment.
Following the video instructions I mixed 5 ml of 25% NaCLO2 with 5 ml of 5% HCL.I couldn't use a syringe to measure the components as both components came with a built in eye dropper in the mouth of the component bottles.so I used two 30 ml cups with measurements in 5 ml marking as a guide to pour 5 ml of both components into the two separate cups before adding the cup with 5 ml of HCL to the other cup with NaCLO2 and then stirring the combined ingredients and got the instant coloration change. I poured this into the small compartment. It covered maybe half the compartment at a very low level of coverage.
I left it in the fridge for close to 24 hours.
Then I tested it using the InstaTest strips recommended in the video. After using a 30 to 1 dilution The test strip matched up 50 and not the 100 at the 30 to 1 dilution meaning I had 1,500 PPM instead of the 3,000 PPM the video said it would produce. I'm guessing, with all your experience, you knew that would happen.
So, instead of starting over I ran a second reaction again using the amount of ingredients as the first reaction.
After testing the second batch it didn't quite match up with the 3,000 PPM but I'm guessing it could be close to 2,500 PPM.

So I'm a day and half into AK's protocol C to get my body used to ingesting.CDS. Instead of using a 1 liter bottle I'm using a 500 ml bottle to which I add 5 ml of CDS and doing that twice a day.

You've mentioned a good CDS tester on other posts. If all goes well, I could see the need for a good CDS tester down the road.

I am thinking of trying this same receipt again but next time uses 10 ml & 10 ml as opposed to 5 ml & 5 ml the video recommended..

In the end I might have to use your quick 3 hour CDS method next time..
Jim in Canada. 

Jim, if you use 4% HCL to activate MMS for CDS, you have to make two infusions. About 1500ppm the first and then about 3000ppm after the second infusion. 

If making Quick CDS, follow the recipe as below. Be sure to put the CDS water in the small compartment and the reactor ingredients in the larger, because the solution depth must be 2mm or less. MMS:4% HCL ratio is 1:2.
