Randy was spot on - average the tracks and use the average for each corner.
So if you had 16 trackers 4 for each corner you would average each group and
then apply the result of the tracks to the 'cornerpin to'
with an expression linked to a knob to offset the result should it drift
slightly should you wish.
Here's a tool I made for average tracks and other stuff. Very clunky maths but
back in my early days of Nuke and pre python.

help "This node has a few common maths tools:\n1) Jitter - calculates the
jitter value from 2 curves after you have filtered the 'smoothed curve'. This
also includes the curveTools average intensity node so you can use the inverted
result in a maths node to remove colour flicker\n2) Average - calculates the
average from up to 16 curves, good for multitrack points used around one point
to ignore grain\n\nUse the results in other relevent nodes.\n\nmore may be
added at some point"
