Riddle me this.   Yeah I know this is a little long but humor me please. Why when we need to make step cuts are we still generating code that has an index move fore each cut? Why is this?

Here is a simple square with 4 steps and the MV generated code. 55 line and lots of redundancy and those extra index moves.  Altered code at the bottom of this, look at the difference.

The altered code does not index between each step but rather ramps down to the next cut.  I first noticed these extra index moves in 2007 after  coming from another CAD/CAM package, it bothered me then and now in 2023 I have to wonder if I am the only person who sees these as a waste of machine time.  I thought MV was all about efficiency.
