Why measure UVB flux when you want to manage Vitd3 p.synthesis

This paper explains why it's more appropriate to measure UVB flux than to take UV-Index and try to make inferences on the amount of VitD3 photosynthesis is going to occur in the reptile's exposed skin while basking.

I chose to set up based on UVB flux , based on the ideal level of UVB flux for a eastern and northern BTS and eastern water skinks 120 to 180 microW UVB flux / sq cm. My Preference is to use a DIRECT measurement rather than an inferred one.
Note that the model 6.5 is tuned for mammalian vitD3 p.synthesis , not reptilian vitD3 p.synthesis.

Not that trying to infer the level of VitD3 synthesis from UV-Index readings is bad ..

Compare Model 6.5

to Model 6.5R ( is repackaged Model 6.4 )

Model 6.5 undercompensates , Model 6.5R overcompensates when comparing the meters calibrated responses.
