I agree with you that comparing viracidal concentrations to blood levels is extreme and possibly unfair.
These illustrations are helpful to try and understand minimum dosing, most effective way to support the therapy, and duration or how long the therapy should actually last!
Even Miracle-Mineral-Supplement dosing patterns and durations vary depending on who you talk to. I have seen maintanance dosings, periodic dosing patterns, extreme but short term dosings.
The theme remains the same for me!
If we can't prove mechanism of action then we should cover both bases not just pick one of the bases to stand on.
Who wants to leave anything to chance if you have cancer, M>S>, etc.?
