The higher the value of the point the longer it takesa 16 muni point will be longer than a 10 muni point which is longer than a 5 muni point.Strategic points cap the fastest. Even faster than VPs (which at least are worth something) Strategic points are usually those annoying points in between high value points. thats all that makes them significant really.
If anyone know or figures out the time required for the different "sizes" of resource points and SPs for that matter please post.
