I definitely do appreciate Your work and findings, doing so for years now, Ted.

Thank you very much!

Do you have the spectral distribution graphs for your LEDs? Be interesting to see if there's a correlation between that and your numbers.

Sorry, they're cheap chinese crapito from a local hardware store. They don't look too bad through my home-made spectroscope.

Although You wrote, these LEDs do not look too bad through Your homemade spectroscope: I think that even the most expensive "high end" (warm) white LEDs do not emit a continuous spectrum.

Here is my measurement of a 3500K high end LED floodlight, using the spectroscope:

The spectral response is continuous, meaning no gaps.

A lab test of the same model:

Note: the y axis is radiometric, not photometric like my test.

Still no gaps, though.
