Thread: Nodes = waste of time.

Nodes exist in the angular rate and cross velocity but they don't co-incide and they only exist at one point in the distribution, e.g there may be a "node" i.e. a low point, in the angular rate at the mean, but the cross velocity may be at a higher value than elsewhere, and mean values represent the average across the population, there is actually a range of values higher and lower, and 1 standard deviation from the mean you will then have a much higher rate

Nodes sort of exist but you can't actually use them. Manipulation of powder charges doesn't Manipulate the angular rate and cross velocity predictably
