BFL, that is valuable info! The battery was full when I did this test, so that may explain why the voltage drop was so slight.
I should deplete the battery to a 50 percent state of charge (around 12.1 volts) and then re-try my side by side comparison of the two cables. I suspect that the drop will be more than two percent.
And LittleBill, that's a good idea, but the controller is built in to the portable panel and can't be removed.
at the end of the day it doesn't matter, even if the 75 foot cable had 15% loss, if it gets 50% more sun then the 40 foot cable, your still going to be ahead.
