I would say that you are really not suffering much from the extra darkness, at least I can't see any errors from the GPS track. So nice work there.
On the näsinge downhill intervals. Would you count your #6 as a mistake or not? You didn't really slow down, but you needed to make quite a big turn to get the control. I'm really only asking because it was the closest I could find to a mistake on your maps from today.
Of course, I count this as a mistake! Practice doesn´t make perfect. Perfect practice does!
Diffuse terrain there, behind my orienteering and lazy with compass. Not a good combo.
