Question about DMSA protocol

I have a question about using DMSA/ALA for mercury detoxing...

I think it's supposed to be 3 days on (every 4 hours, even through the night) and 4 days off as a rotation.

My question is, if one if not getting any major detox symptoms, why bother with the 4 days off? If one has a lower level of toxicity, would it be harmful in anyway to do 7 days on, 3 days off or another schedule where there are more days on? Wouldn't that help detox faster?

If one starts to experience symptoms, I understand the reason for taking the break but what if a person is tolerating it well?
