OGSF 5.0 v EPHRA 5.5

[Shannon]

How much more red is the red to the left side of the red band in a rainbow than the red in the right side of the red band in that same rainbow?

In fairness, this is actually quantifiable if you focus solely on wavelength, making the comparison about 740nm before it gets to infrared vs. almost 620nm before it noticeably gets to orange according to Wikipedia. Yes, the difference is microscopic but the ratio is 37/31, a little over 1.19 times wavelength.

Maybe a better comparison is The Sun vs. Betelgeuse or something, compare two stars.

What if I say that red really extends to 741 nm? Color perception is subjective, no two people perceive the same wavelength of light exactly the same way. That's my point. It's subjective because we don't have a real quantifiable way to measure it. You say it's "about" 740 nm because 741 could be red too. And 742, also. Depends on your eyes and brain and what you have come to understand as "red".

Likewise, subliminal power is hard to quantify. Even if we know the words per second. Or in this case, we can estimate them only.
