In order to make sure our RTC/timing isn't drifting too far off, we need to do a table test where we hit or drop something on the table at a very specific time (which we write down) and then check whether the time we get from the SD card matches the time we recorded.
We should also do a test with periodic motion to make sure that we don't have dropped reads - if we move the Sharkduino back and forth in a predictable way, will the results we get reflect that?
