Consistency over accuracy.
Anything else is just chasing the numbers.

Agreed to a point, however what if the readings you are getting off your test kits changes each time you test. Today you test the alkalinity at 7.0 and tomorrow you test it at 8.5 but it is only test kit error and the true alkalinity didn't change.
I am only searching for stable values not overly concerned if my alkalinity is 7 or 8 but I don't want it jumping all over the place.
A year ago I found out that my 6 month old Sybon salinity calibration solution was way off. I thought my tank was at 1.025 and it was actually at 1.030.
Sending off the samples to ATI is just a way of finding out if my test kits are giving accurate numbers.
