one advice: spend all your time and effort to learn Cf-edit better and make 1 very good map instead making lots of these quite bad maps.. =) And get a course-setting lession!
I know when its not my day, i'll do the other comps tomorrow. the contour interval was waaay to small. If in rl the interval is this small, then you need to do the shrinking thing because ocad convert ignores alot of the detail to an extent. ie small hills become non-existant
