It takes 10 minutes to boil water. Sometimes it feels like way too long, but how often do I boil water, and do I really need a $400,000 nuclear reactor in my kitchen to boil the water in 2 seconds?
These units are testing canna, water, air, whatever...and they will most likely not be used 5 or 10 or 15 times in a given day. They'll be used once, and put away until next time. TM, if you think 3 minutes is too long, then God love you. I don't get the impression that analysis speed was the issue today.
I'm beat. There's no logical reason at all for today to have happened, IMO. Everyone have a great weekend.
