Nope you didn't add enough plots SE...

[EaMett]

There is absolutely zero promise that this method will work and it will in fact not work at all on any server with a moderate amount of competition or where plots open infrequently.

There absolutely is. Not only is there but it's even a strategy that has a better return if you're on a high competition server. The more people crowd around a single plot the better a strategy this becomes.
This strategy comes with the caveat that it will statistically take about 10% more camping time, ie a 10h single sitting camp = 1h camping/day for 11 days. But you can further reduce that 10% with a variety of other strategies. Some of which aren't even available to people who camp for entire timer durations. In fact, you can technically reduce your time spent camping in HALF compared to someone who sits out the full duration of a timer.

Not only that but you greatly reduce the risk of wasting your time because of a relocation as well (a 20 fold reduction!), which opens you to farm some of the riskier plots like shirogane, and lavender beds as well (both plots you shouldn't touch with a pole if you sit through full timers, especially on a crowded server.. Which again, people don't seem to understand).
