Hey Eric,

Perhaps you could try anchoring your hand or wrist in a different place.

Setup a metronome and run through a series of 4 beat measures where the root of those chords is the first, then first and 3rd beats of the measure, adjusting the speed as necessary.

[br]Last but not least - it sounds a bit weird but maybe try closing your eyes. Let non-visual cues guide you in. You'll be all over the place at first but if you find the right anchoring point and can be patient it may help.
