FWIW, if you have several tracks you want to average onto one cornerpin (or anything else for that matter), check the T (use to calculate transform) next to each tracker, then in the Transform tab, set the transform mode to stabilize and the centre knob will be the average of the 4 trackers, saving you the trouble of writing an expression.
