No problem - you live and learn. BTW my comment wasn't about the intention of the organisers, rather my impression/feeling. I may only have had this feeling due to my lack of experience in orienteering in this type of terrain - which is fine, part of the reason I am doing this sport is that there is always something new to learn and improve upon.
On control 2 I was definitely on top of the crag/control and looking down, expecting to see the control just to verify I was in the right place before climbing down, just in case I needed to relocate myself. Which is what I tried to do, as I wasn't seeing the control. Problem was - relocating didn't make sense as everything told me I was in the right place, but I reminded myself that one tends to be biased and "makes the environment fit" where one expects oneself to be, so I climbed down and ran up/down to check the surroundings. Once I did that and returned to the crag, I saw the control tight right next to the crag.
In fact, control 4 was similar - I did not check that one from straight above as I got to it at the side, but on that one I did have to climb down before I could see the control.
Control 5 was similar to 2 in the sense that I did look straight down from the top, could not see the control, took some time to look around, the difference to 2 was that this time I was expecting that I might simply not see the flag, climbed down once I reassured myself that I was in the right place, and the flag was there. So as you can see, I am adapting even within one race :)
In fact control 5 is visible on this picture:
