In reply to JemC: aye accuracy needs to be within 10%, no conferring allowed and even when it isn't your leg you are expected to know where you still are. only trust your own navigation as some people can give the impression they are shit hot, yet are all over the place which makes things difficult.
I found pacing harder to master and so made up a little card with times for distances and speeds so as not to have to calculate it in my head and it fits in the corner of the map case.
note that days spent climbing mountain routes e.g. on Beinn A Bhuird or Lochnagar do not count as quality mountain days, and neither do winter days count for the summer ML. This was a real bone of contention for me as I hadn't accrued enough quality summer walking days (I'm not a munro bagger) according to these criteria, yet my navigation etc. was spot on. The river crossing section is also a bit dumb and I think they are reviewing that for change in the future.
it's a great experience though and one award they certainly don't give away.
