The first question would be why is this your 3rd time doing the NLP. If it's because you are doing them back to back with resets, then it's time to move on to INT programming (which a 4-day is one example of). If the 3x is just because you had breaks in training and then started up again, and are still solidly making progress in the NLP, one option is to rotate your power cleans through 5x3, 7x2, 9x1 (or thereabouts).
