Computational cost is not the only reason.  It helps people understand 
the fact that the sampling is, in fact, discrete if the first few curves 
they see, as absolute newbies, show some visible sampling right off the 
bat.  It keeps them from forming an incorrect mental image of what this 
program will do.

That depends, as always, on what one expects.  I think you'll understand 
better if you replace the default tic format with "%+h" and re-do your 
exercise.
