... in hindsight I should have left a larger foot on it,
Over time I personally have stuck with about 1/3rd. diameter for platters and bowl base configuration, although in use they balance quite well on much smaller bases and there would appear to be a regular aesthetic trend promoted to produce smaller dimensions, I'm happy with the I/3rd and the overall stability it produces for 'users' as opposed to just display pieces.
Something in the region of 1/3rd. diameter also seems a good compromise on any rocking resulting from warping, only bettered or controlled completely by deliberately going for a three point suspension.
