Also.... if there seems to be a good amount (more than normal for your T) make sure the pickup tube is hanging straight down from the cap. With the pass thru design it’s possible for it to hang a few degrees in one direction or the other which could cause it to prematurely start getting skewed results. Possible as well that the tube is getting pushed out of plumb when sliding the drawer shut.
I put a small piece of painters tape on the tube to secure it to the cap. Then I just twist the bottle away from the top instead of the cap from bottle, so far it’s consistently getting to 18-20% before results jump from low reagents. 3 B/C reagent changes since semi-securing the tube/cap
