Four troublesome controls out of 15 in total.
#4 would have deserved more respect - I just ran roughly out from #3 and started to look for #4 on the wrong hill. Should have used the big stone and the big path as intermediate checkpoints.
#9 was located quite low and close to the yellow field, so the approach from the powerline and cliffs above is completely wrong. Should have instead taken the small path all the way to the corner of the field and #9 from there.
Inexplicably lost track of the hills on the way towards #10 and looked for it already on hill nr 2. Then a poorly planned direction out of #10 towards #11 through slow terrain. Staying on the white area of the map would have been much faster.
