Bottom line: remember from grid to mag, add, from mag to grid, rid.
Nice mnemonic! I've never really felt the need to fiddle around with the couple of degrees difference between mag North and grid North. I doubt whether you can take a bearing with a Silva type compass accurate to within 2 degrees anyway - to do any better you'd need a prismatic compass. As long as I'm carrying enough food and have shelter, I'm not particularly bothered with compass navigation. I've ended up in interesting places on the occasions when I've got lost! The last time this happened I was on the complex ridge system in the middle of Arran. The mist was coming and going and I hadn't a clue where I was on the map - even if I could be bothered to get it out and struggle with it in the wind! I just shrugged my shoulders and flogged on knowing I would get to the sea eventually - which is what happened. Mind you, it would have been a longer walk to the sea from the Cairngorms!
