Procedural Foliage/many instances reduce wind-effect

Hi

I am using the PF spawner to create lots of trees in a landscape.
The trunk/branches and the leafs are having the same sine based sway effect, and it works perfectly when I just inserts a couple of trees into the landscape. The sway is controlled by material instance parameters and not by a directional wind source,

I have found that the more instanses the PF spawns the less the wind/sway effect, so when its like 10 trees its fine but at some point the sway almost disapears.

I suppose that if I manually create a lot of instances the problem will be the same, but im not sure.

I have read some other post about the same problem but no solutions.

It seems strange that the number of instances can influence each instance.

I have attached part of the material graph for the trunk, which have the effect to bend the whole trunk based on some sway parameters.
