55 will be safe, look at how many lower scores have to come under 55 to knock it out, that won't happen before the Qualifying ends.
I have tried to avoid playing the stroke play outside of the Qualifying because my assumption is that WGT will use the layout that we use for the qualifying as the layout for the Open, changing winds and green speed as they did last year at Pinehurst.
If they move to the layout that they have for other play, my notes will be screwed since the distances are all different from that set of tees.
It would be nice to know what they will use. If anyone has evidence of which way that WGT will stack things for the Open, please respond.
Thanks.
