found 2 packs, (total 12 cells) with these cells in them, every single cell when discharge tested from 4.2v to 3.2v at 1 amp all return between 2600mah - 2700mah. seems kinda weird.

Have that to, lots of them over 2700 mAh.

Datasheet link appears to be broken. Try this one - http://grobotronics.com/images/companies/1/datasheets/ICR18650-26H.pdf?1511772798728

Also check the max charge current and discharge current, they appear to be higher according to several sources.

Might explain why capacities tend to read higher at 1a discharge.

So if I use 1300mA to discharge, the mAh outcome would be correct?

If yes, does this mean that if I use 1000mA I should divide the outcome by 1.3 to get the correct capacity?

Or is it not this simple...?

Not quite. Cell capacity does read higher at lower discharge rates. Look at some of Thunderhearts graphs.
