Preferred body temperatures data from Wilson , the Preferred Body Temperature (PBT) for Bearded Dragons is 35 degC (95 degF).
Their Preferred Optimum Temperature Range (POTR the range of temperature needed to maintain normal body functions) is 35 degC to 39 degC ie (95 degF to 102 degF).

Relationships between PBT and ambient temperature from Mumford.



and Behaviours based on ambient temperature from Thompson.

Have no clue how the first chart relates at all to beard dragons.

Your second "chart"

You've edited that chart. It's not the original.

It's in reference to body temperature not ambient air temperature.

It's not even a chart on bearded dragons.

It's based on 40 year old observations.

I ask again, would you cook chicken in the oven at 165f because the internal temperature you want it to get to is 165f?

Here is an actual experiement done on dragons body temperatures.

In the study most dragons were found to not seek shade (cooling) until around 40c+. As indicated by not only behavior, but a measured increase in hysteresis; the main goal of the study.
