Finding Arrow Nodes... Then What?

Okay, so it is my understanding that the nodes of an arrow are [two] points where during the arrow's flex from launch to target follow each other in the line of flight [provided flight is tuned], and I have a basic understanding of a technique for identifying arrow nodes... But then what? What do you do with this information; why is it "important" to set up/tune? Are you trying to line up the node with the plunger, or having the plunger between the nodes; before/after?

Yeah, I'm probably not going to get a great ROI if I pursue the efforts, it's a curiosity/learning endeavor.

But then again, I'm the guy who couldn't hit the floor if he dropped an arrow from his quiver, .
You're one of those too??-- I tho't I was the only one..... :) Interesting fun question what does the location of the node mean? My guess is their location tells us something about how the tip wt and fletchings etc affect the arrow dynamics.. Fun to do a node location on a shaft before adding tips and fletches and then after the arrow is built to see if it changes???? but a so what answer I don't really have. Just more fun with the physics of arrow flinging.. I wonder if marking the top of the arrow at both nodes so it can be seen as you draw would constitute a sight violation for BB??
PS I did this the other day-- found the node on a shaft then after point was added and the node shifted towards the point, did not fletch the back end but did add a nock it shifted back a bit- so based on this very antedotal test how you build your arrow might well affect nodal points- now what does that mean????
I think he meant that, in general, 1" to 1.5" of shaft in front of the plunger will cover most applications. At full draw, the node will be behind the plunger. This allows at release for some travel across the plunger before the arrow comes off the rest. IIUC.
that would be for Olympic recurve right? since with BB we never draw back that far. So if this has real meaning then now as a BB shooter I have an excuse for poor arrow flight to the target.
And any good slo mos of BB shooters?? I agree with r-d that for most BB shooters this is incredibly difficult to test because of the inconsistencies of shooting at least at less than stellar levels and probably even then. Maybe we have to turn to slo mo to see and analyze. Interesting idea about the role of brace height and upper node dynamics. The plunger saves a lot of us and perhaps it is moot for most of us but still interesting to know.. Maybe a hooter shooter kind of set up but with the bow vertical????
Thanks for posting. It is still too fast and not high res enuf to see what is going on microsceond by ms.. the op did as good a job as they could with this and you can see some of the early arrow dynamics but it would be great if we could get one of those ultra high resolution slo mo cameras that can follow bullets to look at the early dynamics from all angles, Again I think shooting from a hooter shooter type of set up and then comparing it to a pro BB shooter would also be great. OTF shooters all have a bit of a pluck even on the best of days and that has to add to the arrow dynamics. The physics of arrow flight is very interesting even if it does not change the way we shoot.

This is a good example of a well tuned recurve and how the nock disconnect is timed.
Nice video and much clear and one you can go thru frame by frame more or less.
