I got lucky, I approached from the west around the (slightly) steeper stuff and happened to spot it as I was coming around from the south. I wasn't sure if it was mine!
Splits upload on TBT is a bit weird - shows Jo Anna as taking 5 seconds from 2-3 and even E Plummer as going <2min with me in 3rd at 3:19. Also Graham Harris and E Plummer are missing six splits each, which may explain Graham's really good time. Jo Anna and Graham are showing phenomenal splits (<2mins) on the long leg 6-7.
Well, silly me looked at the control descriptions and decided to deliberately approach from the north.
I did wonder about Graham Harris as that performance did seem well above par. But then they did have people who did a lower course listed in the H1 results earlier in the day so I thought that may have been the explanation.
Sounds like Graham and Edward have both done either H2 or H3 and been put into H1 for whatever reason. Doesn't explain Jo Anna's splits though or how they got legitimate results despite not visiting half the controls. Computers are weird.
