Must be the first time me and you have disagreed on something so fundamental on here IIRC!
My reasoning is that higher resolution allows you to be more accurate with the mapping, and at the extremes of CR that is particuarly important, however I very much doubt I agree with it to the extent the person who said it to you does from how you are wording that.
But giving your example of 5 degrees, you could ask for 5 degrees before, but you got it in LOTS of places, which meant you ended up having to dial in less advance than you wanted in areas of the graph just cause you didnt have the resolution to do it accurately enough at all the points you really want to.
