Extra super light cleans aren't going to drive improvement. It's also real easy to do super light cleans really wrong and not notice because you a) get away with the rack anyway and b) don't get enough feedback from the weight during the movement.
It depends on where you are in your training, but a better option would be something like adding extra clean training at weights you can keep technique together. You can do this as warmups for deadlifts, or just as an add on. You might do this for several as perfect as possible singles - clean practise - at a weight that you might have done at the normal clean day as triples.
But say your deadlift is about 335 and you cleaned, say 115-135 on your first clean day, then forget about 55# cleans.
