Guys I take your point, there's no substitute for a good quiver of skills, but practising precision landing at an intersection is much safer.
Its a bit like turning the fan off to do a PFL. It adds a whole new dimension to the exercise, but isn't something that you would sanely do.
I'm sure that many people fly from fields where you can safely glide onto the numbers, with no risk at all. Most of the fields I fly into have neighbours or obstructions and I wouldn't want to take on the additional risk, just to prove I could do it.
