Opinions please, at what point would YOU have initiate the go-around.
Opinions??? For something that is enshrined in regulations and airline procedures?
Someone before showed the approach plate for this approach, there is a Mapt clearly visible on the chart, this is where they should initiate go-around. And by the way it's altitude (MDA) is depicted as 465 ft, you have no business descending even a foot below this altitude if you can't see runway.
