"There are numerous warnings (not just instructions) about using the Sodium chlorite without first activating it and I think it wise to head those warnings"
If you have seen such warnings from Jim Humble, or some other practioner, would you please post them here? I would appreciate it.
" I am aware of the use of extremely diluted sodium chlorite in stabilized oxygen products (at 1/18th the concentration per drop of Miracle-Mineral-Supplement solution)"
I do not know where you get this information, but Stabilized Oxygen products generally run around 3 - 5% NaClO2 solution, compared to the 28% NaClO2 solution in the Humble stuff ... so the solution is about 1/5 to 1/9 as strong depending upon the specific Stabilized Oxygen product you are comparing to. You keep mentioning 1/18 ... are you somehow comparing the activated Miracle-Mineral-Supplement with the unactivated Stabilized Oxygen?
"I believe this product is best used as Jim Humble describes---activated with 5 times the amount of citric or acetic acid"
Jim describes using unactivated NaClO2 ... in fact he used it himself, for water treatment and for malaria treatment, and he only switched to the pre-activated form when he discovered that it was even more potent.
