Final answer:
The characteristics of a simple and cheap method that can have no big slowdown but can completely miss periodic behavior and has a high error rate is the counting chamber. The counting chamber is a tool used in biology to count cells. It is easy to use, relatively fast, and inexpensive. However, it may not work well with dilute cultures because there may not be enough cells to count, and it may not accurately capture periodic behavior.
