But every flight you do results in you getting some practice. Well, so long as you sit in one of the front seats and are sitting upright and awake.
This whole debate is meaningless re legality of single pilot IAP flying.
There is another angle worth a mention: most pilots with an IR fly IFR all the time they fly outside the UK. IFR is far easier. And ATC expects an IFR flight to fly the IAP. To argue as some here do that somebody will hit you because you are in VMC and therefore this is illegal, and therefore you should never fly an IAP but, presumably, either cancel IFR and fly VFR to land, or ask for a "visual approach", is nuts.
