said the better the orienteer the better their ability to cope with bad mapping.... you must be well used to it with all your Beecraigs orienteering ;-)
Bilbo used to encourage team members to spot mapping errors and laugh at them as they spiked the control anyway... same stuff!
Interestingly mappers often run better on bad maps than non-mappers - probably because they so often have to deal with poor bits of base map or old maps.
There was actually nothing wrong with the mapping it was just that the map was very out of date. So when we tried to test route choices as a group it was impossible to execute some of the routes as the paths didn’t exist any more. There were also new paths, paths that had dramatically changed size and paths that started from the same place but then continued at a different angle - all of which made it confusing. I’m not usually one to have a moan about the map but when trying to run a long leg on paths (when you have spent time discussing which route is the best before and after) then it’s a proper pain when the paths aren’t correct.
