As Tower Supervisor, I once did 7 runway changes in one shift. If I remember correctly that day we swapped ends four times as two massive CB cells came through throughout the afternoon and evening. We alternated on westerlies at 1500 as usual, but then later on in the shift we had to de-alternate due to a problem and then swap back to the alternation programme once sorted.
