Martin is a Swiss O' trainer who has spent some time thinking carefully about orienteering and map reading. I roughly described some of his ideas a few days ago as a "coming attraction."
I'd encourage you to go to his page, download the discussion paper, and give it a careful read.
I also want to thank Martin for thinking carefully about map reading, writing his ideas up in German, writing an English version, and giving me a chance to preview it. I offered a few suggestions for text editing. You'll see that Martin thanked me for that. But, really it wasn't much and I owe him a big "thanks" for the work that he put into.
