Precisely, and I believe that is what I have been observing for the last 8 to 10 hours, a top 'toppling'. I knew I'd seen that kind of erratic behaviour somewhere before. That's the reason I decided to make my 'theoretical' post prior to the 11pm. I postulated that Wilma would continue to topple more and more frequently along her track, giving up energy on each cycle until she de-intensified and slowed sufficiently for her ERC to start afresh. I pre-supposed that the toppling was initiated by a breakdown of the eye with a consequent loss of energy due to the revised temperature differential within the core.

A sort of theory based upon my observations for what it's worth. Comments?
