Oh I forgot to mention a
very important part.
Those plots are only the magnitude of the pickup output due to the velocity of the string. It doesn't include the response of the guitar electronics like the resonance of the pickup inductance with the cable/amp/tone control capacitance.
The real output of the guitar would be the plot above multiplied by an electrical response of the guitar electronics below (typical).
I've been very busy, but I plan to work toward an analysis that includes the pickup position COMBINED with the response of the electronics. I don't know if anyone would care, but it is a personal goal of mine.
I have always been curious how Leo determined the Tele bridge position and slant. I'm sure it was experimentation. It is definitely a "sweet" spot. I bet he would flip out to know we humans could simulate that with a computer today. Not that looking at plots would tell you if it sounded good!! It's just an academic exercise.
