Ya I cant say I agree.
I agree that the basking lights help with digestions sure, 100%. However reptiles will still bask after they are seemingly done, they still need heat I would argue long after you think they are done basking.
As Ruthless said, the principle is fine, as long as your temps are higher later in the day. For most home environments that is not the case, if your house is a constant 70, you need a basking light throughout the length of the day. Reptiles are cold blooded, they do not unlike us generate their own body temp. By doing as suggested, we are both subverting a naturalistic habitat, but also removing choice from the animal.
Your enclosure should be providing a temperature gradient, and with the solution of shut off the basking light, your cage is now what 70 all day long?
You also have to put into your thought the average keeper. The Average keepers around here (the new guys, the ones that are not involved in the hobby aspects) will have a T5h0 UVB and a Basking light, say a Halogen. You just told them to turn off that halogen, at 10am. Now the Chameleon will not only have a super dim cage, but the temps will be 70 cage wide. This suggestion is terrible for that keeper.
For the guy with Quad T5s, whose cage temp, will still be up in the high 80s, at the top, the solution is not such a big deal. That was probably who bill had in mind when stating that. Its still not a natural state, as the heat is not highest at 7-10am. Thats moving away from the Natural Process we should be moving towards.
Lighting is a diffrent subject, but sense we touched on it, I feel this should be brought up.
"No artificial lighting system in the world can provide the full spectrum and intensity of natural sunlight, its subtle changes in color as a day progresses, or the sun’s movement across the sky. For these reasons alone,
the more natural daylight a reptile experiences, the better. “Natural daylight” may not always mean full sunlight; a herpkeeper must aim to provide species-appropriate lighting."

I have always agreed with that sentiment 200%. Contrary to that article, as it is old, things have changed. We CAN Recreate the subtle changes in color throughout the day, we can change the heat throughout the day, we can recreate a pretty close to the Sun setup.
I also agree with the "Naturalistic Hydration" at its face value. However in the case of this thread, we are ignoring reality of nature, for some perceived better way. So the old way wasn't Natural, this way is not like nature, so what differs them? We should be pushing for naturalistic keeping, but thats not what this schedule does.
If anything, this "Naturalistic" humidity plan, steers further from nature.
We have seen the weather, the temps are hot all day, getting hotter in mid day. the humidity is high All day, getting higher at night. There are frequent short showers of Rain, throughout the day.
Sounds alot like the old way, basking all day 3-5 mistings per day, or whatever. So instead we exchange that for a higher nighttime humidity? For that we give up the average day temps, and the rain that are proven to exist as well?
