If I were doing this, I'd do it at the best time for me. After some sleep, my goal is ready, for example testing a product, and when similar-type things get upvoted. This depends a lot on niche, I think. For Ask though, I always visit it when also visiting the homepage, as a lot of interesting questions get posted. Perhaps for Show an optimal time is more critical?
