OK, just so anyone outside F9 is wondering. THIS CHANGES FREQUENTLY! There is no rhyme or reason. There is absolutely NO consistency for percentage of 1, 2, 3 or 4 day trips for any particular base. One month could be mostly multi day trips and the next month hardly any. This goes for EVERY base. If you're making decisions based on this primarily - first of all, you're stupid - but you will be dissapointed.
