Turns out green is the root and brown is a tap
You can ignore this or not, it only matters to a thorough understanding of the LP bass, not low Z pups. If you follow the schematic, it doesn't matter.
I had measured everything from the brown wire, so from that perspective, the first tap is red at 25 ohms and maybe 685 turns, and the second is blue at 52 ohms and maybe 1255 turns, and full spool, green, 115 ohms and maybe 2700 turns.
But, in trying to draw a schematic for my installation, I realized brown had to be switched in and out by the coiltap, with green always hooked up, rather than brown always hooked up.
I have been speaking of red as the lowest tap, when it is the highest, and of blue as the highest tap, when it is the leanest.
I would now array my data set this way:
First tap, Gr/Bl, 61.7 ohm, maybe 1437 turns
Second tap, Gr/Rd, 88.9 ohms, maybe 2007 turns
Full wind, Gr/Br, 114.1 ohms, maybe 2692 turns
Same results, just presented with the perspective of green as the common and brown, red and blue as the taps, in order of decreasing energy.
What does this mean for the sound?
The leanest coil has more wraps and the progression of taps is not as radically different as doubling the winds each time. The ratio is more like half again as much and a third more.
