Here's the chart. I have the excel file for it. It's quite involved. Someone put some serious time into it. Don't recall where I came across it, but it's credited to bb_94401, a forum member who hasn't posted in quite a few years.
Pianotuna posted the excel file on another forum here.
The chart places a 0.040 difference between 75 and 100%. It didn't take Trig to come up with my estimated SOC differential of approximately 15%. Assuming, of course... that the chart is accurate.
One could run his own experiments by cross referencing resting voltages with SG readings.
