from my understanding of the 'ol decoction is that the mash out step is done with more wort, less grains, that way your not bursting the grain, just heating it up to mash out temps without having to infuse with more water (for those with limited mash tuns).
and yep as others have pointed out, use some form of software to help figure out how much to remove.
decoction is also helpful if you have missed your step temp - do a small decoction to achieve the right temp .. done that a few times
