Lets you specify how accurate movement detection should generally be.
You may wonder what this setting is for – after all, precise detection is always the goal. However, very precise detection also requires maximum processing capacity. And maximum detail is necessary in only up to 50% of all cases, because of the way in which Mercalli works.
Consequently, you should only increase this effect (= detail precision) whenever the result of the previous stabilisation attempt is not yet satisfactory.
