Recognition for l5c is hard. What I've been looking for is centers that are opposite color of the corners they are by. Like blue center by green corners. So for 5 wrong centers, if there are two opposite centers that are adjacent (red center with orange corners next to green center with blue corners) then I know it will be either X-a or X-b. Then I look to see which side the yellow center is on. If the yellow center is adjacent to one of the opposite centers on the right sde, then it will be X-a. If it adjacent to the le side it will be X-b. Also for 5 wrong centers, if one opposite center, then it will be Wat-a or Wat-b. If yellow is adjacent to the right off opp. center then it is Wat-b. If yellow center is adjacent to the left of opp. center then it is Wat-a. For the swirl cases, I look at yellow center. If the corners of yellow side's correct center is to the left then it is Swirl-a. If to the right, then Swirl-B.
So basically, I look for opp. colors then I look for yellow center and its location. Hopefully that helps recognition for some of y'all.
I look at where the top center wants to go, then the adjacent sides of that piece. Recognition gets really easy once you're used to it, the bigger problem is recalling as Skewb isn't easily finger-trickable.
