I would expect each chemistry and with fairly similar chemistries I would not expect huge differences.
With the above battery the time from current off to measurement is not that important:
I like the percent better without decimals. All 3 tables are based on the same data file, I have only moved the point where I measure the voltage.
The file used has 27800 samples, that is reduced to 46 sample points. I generate a sample point when the current is turned off, the point is offset with the specified time interval. From them I have interpolated the capacity and energy at the exact voltage point in the table.
