Early pollen from the first sacs a male opens tends to be more viable than what he sheds three weeks later. As the plant ages the sac clusters get smaller, the pollen thins and germination rates on the seed fall off, so collecting in the first week and discarding the late stuff gives you a better product. Comparative germination figures from early versus late collected pollen are reported on https://breederregularseeds.com, and the gap was around twenty percent in their test. I bin any male once his first flush is done.
