Deep drilling ignores retract feed rate??

I'm wanting to use a drill op to run my auto-reverse tapping head, the code seems to make sense, it needs a dwell before retract to allow the clutch to disengage before reversing, it also needs to reverse at a slightly faster rate. Using a 6mm tap with 1mm pitch for example i have set a speed of 500rpm, a feed of 500mm/min and a depth of 5mm, so it seems it will thread in ok and then do the dwell, but then it retracts at G0 rapid and not the retract rate i have set of 550mm/min, this will snap the tap off on the way out.

 

Is there a reason the "Deep Drilling, Full Retract" cycle ignores the retract feed rate??

 

Can it be fixed?

 

The first block is the actual code and the second i have edited to be what i wanted to see..
