Just messing around.  Say if I were to start a decel at 1nm from an lz starting at 110, to arrive over the lz at 0, etc.  I'm thinking about how this could pertain to a self contained approach. 
 
EDIT:  I figured it out, by messing with speed changes and using slowdown by time, I got it close enough (ie slowing from 110 to 5 at 5 kts per second takes 21 seconds, converted to min=.35, etc.)
