Nick, here is what I found out:

Right – Left: your right or left eye.
CMP: calculated mid point (match between yellow and red-green mixture)
SR: (setting) matching range
AQ: anomalous quotient
B: I have no idea.

As your matching range goes almost over the whole spectrum (0 – 100) you are according to this test a dichromat.

AQ for normal vision is between 0.76 and 1.42, which is a ratio between your results and results from people with normal vision.

As far as I can tell, the results don’t tell anything about if you are a deuteranope or protanope. But as I could read you know this already from you eye specialist.

I recognise Rayleigh’s name, he was an early researcher into optics. I don’t recognise the test or understand how to interpret the results. Sorry.
