Schedules have been recently changed so I doubt another major change will occur to change this outlook. We are aware Ryanair are making a number of cuts across its network in 2014 to allow for significant growth In Ireland and Italy as well as at Stansted.
As well as the long distance sun routes, there are some short sectors such as Derry and Knock which allow for based aircraft to regularly operate 3 return sectors per day. There are also a number of routes operated by aircraft flying in from other bases across Europe (which I think you are confusing and incorrectly referring to as "W" rotations, which is something different.)
So in a nut shell, 11-12 flights with 3 based a/c plus a few inbound a/c from other bases is more than feasible.
