My suggestion would be to install one component a day.  That would sure take a lot of time.  
Seriously, good engineering practice must take into account the tolerances of all components.  Matching components that are within tolerance is almost always a useless activity.  For example matching the current limiting resistors for an LED display.  How much brightness variation can be seen between resistors at the limits of their tolerance?  How much variation is there between individual LED's with matched resistors.  I never notice any difference with the brightness  chiefly because I am interested in WHAT the display is measuring not in the individual brightness of any LED.   Circuits that require a lot of individual  component selection are poorly designed.
However if it lights your wick Darrell, go head on.
