Love it. Thanks for posting!
Here are a couple important perceptual differences to my ear-
Note how there isn't really very much difference across the front until the source is all the way over to the side of the cardioid and the supercardioid. But then the supercard drops off more quickly once the source has moved about halfway back. And the attenuation of the supercardioid is in effect "distributed more evenly" on average across the entire rear hemisphere. Attenuation of the cardioid directly 180 degrees to the rear is greater, but is not as "spread out" as much or as evenly across the back. Both provide some degree of attenuation directly to the side in comparison to the omni, but not that much.
In terms of pattern and how that transplates to taping, I like to think of a supercard used in the farfield (the way we use them, and they way its being used in this example) as being pretty much the same as a cardioid across its front, but having its attenuation spread more widely across the its rear hemisphere. I don't think of it as much it in terms of "rear lobe" and null angles.
Somewhat surprised the nulls and rear lobe-ness are as clearly audible as they are here. An example of good mics with well behaved polar patterns.
Wish they also included a shotgun and a subcardioid.
The non-directionally affected bird ambience is a nice real world touch and more enjoyable than audience chatter!
