Too Many Section Grade Break Labels

I know this question has been asked before, but I have yet to find a good solution.


I am labelling offset/elevation at grade breaks in section views (many, many section views) for a proposed surface.  For some reason, I am getting somewhere around 40 labels for a section that ought to have 5 or so.


Now, I have used the method expressed in this blog: which uses expressions to make label text extremely small if a section grade change is below a certain amount (i.e. less than 2%).


While this is quite clever, it does not work if the labels are set to stagger.  The taxt may be small, but the stagger extension lines still appear!  So now, I just have a ton of crooked lines all over the place.  Also, for whatever reason, labels still appear in my sections for non-existent grade breaks on flat sections (and I mean FLAT, no change in elevation, whatsoever).


I know that I can turn the visibility off for labels that I don't want to see.  But I have a lot of superfluous labels and every time I change the surface I'd have to go back through all of the sections and turn the unwanted labels off again, one by one.


Question 1:

Has anyone come up with a better solution to this problem?  I've done quite a bit of searching and everyone seems to point back to using expressions, which seems like a half-fast work around that doesn't actually work that well.


Question 2:

Is there a way to fix my surface so that AutoCAD doesn't find grade breaks everywhere?  Surface smoothing? Reduce section view precision?


Question 3:

Why isn't there a weeding parameter based on SECTION GRADE CHANGE for grade break labelling, and only a weeding factor based on DISTANCE? This would be incredibly helpful feature (I'm talking to you, Civil 3D creators!).
