It's not just experience to read a map but experience to look at the cloud on the hills and say "I'm not going up there today" and take a lower level route. It's the experience to know when you can't walk due to injury or ill health. I had this on the third day of the challenge when I picked up a D&V bug. A fellow challenger offered to walk with me from Cougie to Fort Augustus but I declined the offer saying that if I did walk I would probably end up a mountain recue statistic. As it happened that 24 hour rest meant I was able to continue walking the next day and complete the challenge, albeit as a partial crossing.

It's experience in all sorts of ways. To many people look at a hill and think "I'll be up that in a couple of hours" only to find themselves still slogging upwards four hours later. Getting pack weight down is a skill, as is working out food and where to pick up new supplies.

If only it were as simple as using a map and compass!

Paul I think your missing the point of the whole paragraph it's self. The navigation was only a small part of the main question, The main part was tit for tat and why complains was issued and therefore tannish people reputation and integrity

So what was the issue?
