what about the peak node? just simple move the slider

check Fabio hair system, I did a node that let you control that based on length of the curve, since was needed to control the root, you can copy paste that vop into your network

dont forget that xcpu is bound by the standards of materialX of ILM, as an example sesi did an implementation for ramps, but that's not the actual nodes coming from the community. has been requested to materialX but well...
