Argument is less typing then 'your point in this discussion' :)

Ok I think I got it.
With the blended corners the blends are part of the same segment profile as
the line.
With round corners the straight line is one segment and the corner is a segment,
and linuxcnc must come to a stop between.
If we had look ahead then the profiles would be expected to give aprox the same
speed.
yes?
