In my experience, waiting a full day for readings is brutal for project timelines. You basically have to build in a buffer for every single test, which adds up fast. Take that with a grain of salt, but it's a real schedule killer.
Man, that's the truth. @the_hayden, you hit the nail on the head about the buffer. It's not just one day, it's the domino effect on every other task waiting on that data. Have you found any tricks to work around that wait, or is it just a hard stop on progress until the meter finishes?
