I test---a lot---but I can run the alk/cal/mg series in less than 5 minutes. Here's a shortcut that works, but if you get an alarming result, re-do the test the meticulous way.
Here's how to:
1. have a logbook in which you write all test results---and the date.
2. look at the last result.
3. assume that this result is going to turn-color in about the same range as the last, give or take a little. So don't bother dropping and shaking, dropping and shaking. Just shoot the syringe-full in all at once, stopping just short of the area that you know is going to contain your result. Let it mix. Then start going drop at a time.
4. if you get a shocking result, before you take any corrective measures, re-do the test the slow way.
It's worked for me for several decades and I haven't crashed a tank yet.
