I didn't get below 500AGL when I performed the FLWOP during my PPL checkride, it was during the EFATO during the subsequent climbout where I did, but not below 350AGL. The examiner was not happy with the paddock I had picked and wanted me to choose another and set up for it.
I've been well into the round out in the LFZ before being instructed to go around during my training however. Lets just say that when an instructor pulls that on you, you don't lie awake at night wondering if you would have made it!
