Blip,
the less precise your navaids, the higher you have to go-around because the greater can be your position error in relation to the rwy and the obstacles nearby.
But if you saw the rwy, re-assessed your position and continued the approach, your old minima make no sense anymore.
You know exactly where you are and you go-around because you can't see rather than because of the danger of hitting some obstacle due to position uncertainty....
In same cases you can even touch the runway during the go-around, right? But what took you there were either your eyes or a very precise approach system.
If English was my language I'd brobably be more clear....
