Pre-rut and seeking generate the most observable daytime movement because bucks haven't yet locked down on does. Once peak breeding starts, individual bucks alternate between 30-some-hour lockdowns (mostly stationary in cover) and cruising bouts that can happen any hour.
Midday sits during peak rut consistently outproduce evening sits for some hunters because cruising bucks moving between estrous does don't follow the dawn-dusk rule. The seeking-phase mornings on cold-front days remain the highest-percentage daylight movement window of the year.
