Wow, that's well off the mini-map! Eggs-traordinary sleuthing Steve. Bravo!
Looking at the overhead course map (with all the holes), that last find at the extremity of the course does create a pattern that looks suspiciously like a "W"...
(it's a bit like one of those 'horrible' eye tests that are misery for the color-blind amongst us!)
... but I like Mags' idea of seeing what happens by superimposing the mini-maps and the egg locations. Sounds like a job for Precision-test man! ... Where are you, Ben?
