the issue that you run in to, and this is specific to the alk test, the drops come out so fast, even when you dont squeeze it, i barely managed to count the 5 drops at the angle i used. all other api bottles dont come out as fast, but the alk solution is insanely fast. so fast that you can lose count in the matter of a half second. i literally could have completed 15 drops in 2 seconds if i wasnt carefulNice vid. However I’m pretty sure the dropper bottle for the API should by vertical, not at a 45deg angle like in the vid. I do agree that dropper tests are probably less reliable due to errors such as drop size not just user error though.
