st8k, I'm not familiar with your exact split, but you can do the boards for 5 x 5 . I would disregard your previous numbers, and work up to a weight that's difficult to do for 5. Then do that weight. Track that PR for that board. Compare 2 board numbers to 2 board numbers, and not 3, 4, 5, etc. Keep in mind that one major advantage of the boards is to find your weakness. So rotating the number of boards you use each week could be a great learning experience for you.
