Most of my current flying is very short trips for aerobatics, upon my return to the field I generally do a stabilised glide approach. However, normally every third or fourth flight I come hurtling over the strip at a variety of heights, speeds, hdgs and then somewhere before or after the field pull the throttle closed and try my hardest to "get her in from here".
If I £*** up, then I do a very low go-around (200') which gives me a whole new opportunity to play the "get her in from here" game!
PFLs down to 500' don't really prove a whole bunch in my book. it is probably the 0-500 bit that will show you how far wrong you were!
