How big are the jumps relative to the bandwidth of an individual filter stage?

If one jumps, will it be so far off that nothing gets through?

I assume crystals used in filters will age like the ones used in oscillators, 
so the "manually tuned" will really require a micro processor to keep them in 

These are my opinions, not necessarily my employer's.  I hate spam.
