At some point for me it becomes a question of managing risk throughout the race. Were those mistakes due to not executing the correct technique to use for that particular CP, or taking shortcuts in executing the correct technique. Or were they due to unlucky circumstances mostly out of your control. If it's the second or the third maybe you are too aggressive in the navigation through that terrain. The first one should happen very rare with our level of experience (we are, like, Awesome) and mostly comes from not knowing particular map's terrain characteristics good enough to select the best approach.
My best racing results have been when I was in a good shape in my mind and felt confident. And I would often be too aggressive, when in not best physical shape to try and compensate some time from my navigation. This could work in some cases, but with 20 - 30 CP per race risking even a little for each control I usually get tripped up by the simple probability math.
Good luck in the sprint. You got the speed and the practice with all this sprinting last month :)
Appreciate the advice! I definitely agree with what you say about aggressiveness; my style is also quite aggressive (bordering on the edge of recklessness at times...) which often comes back to bite me in the ass at least once or twice in a Middle. Perhaps if I was smart, I would start adjusting to fit each race...
