I believe the minimum Alk testing is 4/day"You risk failing accuracy and precision if you use the trident manually without doing the minimum tests - the minimum is 2 alk and 2 combined tests daily. The maintenance on the trident is recommended, and while it is not nailed down yet, somewhere between 18 months and 2 years. The plan is you can do it yourself or send it in, with various options that are not yet nailed down either. I don't find any of this problematic. YMMV."
