Gumball on Subd-Edges not always centered?

Hello to all,
in WIP when I draw a subd-box with xyzCount 3 centered around 0 in top-view and then subselect the outer edges the gumball is not centered anymore.

When shift-scaling these edges with the gumball handles point-symetry gets lost. Same behavior if opened in Rh6.
Maybe I didn’t understand Subd-geometry completely but I would expect the gumball to stay at 0,0.
Hope this is not covered already,

Hi Ferry - thanks, I’ll check this.
I see this - and BiundingBox on the edges gets it wrong as well, but differently wrong, here.
I’m, going to make a wild guess that this is related to how vertices are stored, but I am making things up.
