Interesting to see your routes. You had different (and better) ones on #1 and #5 besides the ones we already talked about at #2 and #6. I wasn't sensitive enough to saving climb, among other things. Also, your comment about planning the course out on the way to #2 was telling. I generally don't look ahead, which leaves me at a disadvantage for planning good routes, and find myself making hasty decisions at the start of each leg.
For the most part the orienteering was pretty easy, both the finding the controls and the executing of the routes. The route planning took more thinking because it wasn't just a matter of left or right, or over or around. There were major choices and then minor choices within each major choice, and then sub-minor choices, much of it influenced by the exquisitely mapped vegetation. Often it was a matter of evaluating each gap in the green and deciding which combination gave the quickest and least physically demanding route.
I certainly have orienteered places many years ago where the orienteering was simple and where the route choices were simple, and where I could have planned all my routes before I got to the first control, but didn't, because then I would have been bored, nothing to look forward to. Here I at least planned ahead far enough to get me to the next sizeable patch of yellow. So on the way to 2 I figured out routes up through #6, and on the way to 5 up through the road crossing after 10, and then the rest of the course on the way to 11. Given the amount of time spent in the fields, and the good footing, planning ahead should have been no problem for anyone.
I was just relaxing in the yellow, I guess. Focusing and finding my place are difficult for me. Working on keeping the current leg in my mind and evaluating a second one at the same time would be a useful skill to work on.
