What is the difference between MMS1 & MMS2 and why are they different if the MMS1 works why would we want to change this?

I was just starting to become convinced that trying MMS1 might be worth the risk of trying something that many other people say is like drinking bleach - Its ok, I understand the basic logic, I'm just pointing out that discovering MMS and accepting it is hard enough - now I'm looking at buckets of stuff that would almost certainly clean ovens and I'm starting to wonder if there really is a strange epic following instead of a serious medical breakthrough here.

- Just saying what is in my mind at this early stage of discovery

MMS1 when activated properly as Jim Humble recommends produces ClO2 (chlorine Dioxide). MMS2 is Calcium Hypochlorite and turns into hypochlorous acid when in water.
