Lane Voltage Variance 2021

Recently there was some concern about the power of the Blue lane. I measured the lanes this weekend and it seems they are ~mainly balanced.

TEST CONDITIONS
--  Power supply analog meter set to 11 volts, and the meter below the monitor showed 11.00 V.
--  I plugged in the cleaner truck controller and the monitor meter then dropped to 10.92 at full Pot (hey it's 420 some where :). The 0.08 'draw' was probably just due to the resistance in the wire from the pot to the XLR plug (the microphone cable wire is only #20 guage; which works fine for the swifter Truck but is skinny for racing - WTH  - has no significant impact to the measurements :).
-- Residual voltage on the meter was +0.08  (you'd think this offsets the Truck pot loss but ... no does not work exactly that way ... coincidence I assume Watson).

MEASUREMENTS  (each done x3 times)
-- BLUE measured 11.05 less .08 == 10.97
-- YELLOW measured 11.04 less .08 == 10.96
-- GREEN measured 11.08 less .08 == 11.00

So Green is not only topographically the most challenging lane, but is slightly hotter (0.04 V) than the other lanes.  The voltage deltas (+/- 0.1 and +.04) are probably due to various factors including:
--  slight length differences in the feed wires to the braid-drops (probably an Ohm or less difference.)
--  Surface impediments (braid juice, dirt, general schmegma) not letting my probes get a 100% perfect contact with the braid;  (Altho my probes have pointed ends and were making good contact).
