No thats not the point, you do not get it.

The center Y point moves in space, as the load on each front line is not the same during steering the kite. Thefore virtually 1 steering line becomes longer the other becomes shorter during steering. (more straith line, more angled line)
The high Y split, introduces same effect to some extend (but in way lessamounts), as the turn accelerator from Bruno.
Instead of front and back you are talking about side to side movement and subsequent leverage.

The front lines would have to be separated like on Bruno’s bar for there to be any change in where the y point is.

Because the lines are right on top of each other the y point can’t move.

It is possible for the vee to move side to side but the vee geometry has to remain fixed at equal lengths above the vee

In Bruno's bar setup, the difference in length between left and right front lines can be quite extreme.
But the Y splice gives same affect.

If you pull with a different force to left and right frontline of the Y, (that happens when steering a kite, one side of kite will be more loaded than the other) basically the center will move out of center and so one line end will be higher one end will be lower.

No a y and a vee are the same, you can’t get a relative difference in height because the lines attach to a common point.

Bruno’s system works because there is a separation of the two attachment points for the front lines.

His goal is to get more twist in the kite. Of course it made a more complicated adjustment procedure, and I bet the bar pressure increased.

Goes back to the original crossbow design.

Maybe you can draw a sketch on how you think the y works like the Bruno system?

No at V. the V point is Firm at the same spot, so lines connection are fixed distances to kite. Kite is firm supported.

At Y the Y point moves to left and right "off center" depending on load on each side of the kite and it will introduce a Warp.
If load is equal to both frontlines, Y conenction stay centered and equal, but during steering that side is loaded and forces are higher, so LE moves up and TE moves down = WARP.


Anyway I can't explain better, just check mathematics, load distribution angles vectors and how change directions.

This how or if split point of Y connector is moving would depend on type of safety system that manufacturer is using?
On Core kite front line are sliding on their roller roller that rolls over this thick power line (used to wear out and could lead to flag out system not working at all)
Duotone has different system on Trust bar in 2022 and older model than on Click bar.

Last question is if this moving Y split point is good for a kite or bad?

Nothing to do with safety systems.....

good or bad, pro's or cons. All what you like prefer in a kite,

Personally I like snappy pivot turning kite with less bar stroke. In that respect high Y splice has some technical benefits and is best choice.
Other than that low V has other benefits, more simple, less tangle risks etc.

As long as the lines are in tension the fixed y point can’t move up or down. One of the lines would have to go into compression for the y point to move.

A fixed v is really just a low y

In both cases it would be possible for the vee to rotate.

In order to have the y point move you need an x

Interesting.. I think the difference is in the relative angle of the LEI with the rider.
With the low V the LEI is always perpendicular to the wind windows radius. With a high Y splitter the kite can have a different angle.
Still I think the added complications don't compensate the difference in performance.
Maybe in bigger sizes it makes sense, bit in smaller kites I don't thing so.

If only someone had made a podcast talking about kite bars and how kites turn ( I think there is some stuff about high/low split points in there too) ? :D
