You did the right thing on 10. There were no attackpoints in any other direction (I tried - for 40 minutes)
I posted my splits, and noticed that except for 4 & 10, our times for each leg were comparable, especially once you got into your rhythm for 5-9. If you take out those two time-sucks we're pretty even.
Although it took me a while to get there, I think I picked the right route to 10, and it was pretty easy to find once I got there. I went to the NW corner of the private property, and then ran parallel 25m N of the private property line (which was clearly marked) went to the second gully by the contours and the flag was right there. If I approached from any other direction, it easily could have wasted a good amount of time. Moral of the story - use whatever clues are available, even people's backyards.
Also, on 11 I elected to go through the orchard to Holt Road as well, and saved a few minutes there, so I thought that was a good choice.
