1. Something was wrong with map approaching Control 2 (specially the trail above it).
2. I think the feature for Control 7 (small depression on the side of the gully) was mismapped and control actually was about 40-50 meters higher that it should have been. It may not created big troubles for people who cautiously decided to go around big gully and come down on the spur. However, I chose to attack from the trail bend across the gully and spent extra 3 minutes researching its side.
3. Control 10 had 3 distinct variants: left via trails and attack from the corner of clearing, straight via green (worth variant), and right via trail and seemless attack from the bend of the trail along the stream and small swamps. Left and right variants seemed equal but it appeared that going right cost me ~4 minutes partially due to the mismapped trail bends and being thrown off the bearing by much. I suspect most of the people chose left variant.
What are your observations?
