Mike: Are you sure it was not #5 that you are missing? That would make more sense.
Yes, no split for #4 is definitely correct. I was distracted from hitting my watch by another runner at #4, and I know for sure that I hit my watch at 5 at the boulder where the control should have been, before locating the streamer a few meters away and then the control flag itself a little farther up the hill. I was moving very well until #7 then really hit a wall at the top of the hill going to 8. I felt like my strength/speed was coming back a bit on 11 and 12, but your splits show that I was still not anywhere near where I should have been.
