Until then, most riders which are new to cycling or are making a re-entry - or are impeded in any way - are unable to absorb any significant body weight with their legs, and that leaves the majority of the weight borne by the saddle. I've observed this on multiple occasions, and am sure you have as well...
this can certainly be a factor. Heck, at the beginning of the season, for probably a month, my tush and hands are more sensitive, and part of that is the fact that my legs aren't putting out the steady output I usually do, so yes, more weight goes on the other two contact points.
there are so many factors involved with comfort, seat comfort no less, but how much one rides and therefore take a certain amount of weight off bum and hands is a real factor. I even notice it when riding with someone who is significantly slower than I am, its hard on the bum and hands simply cuz my legs arent working at my optimum output and not taking the usual amount of weight off the other areas.
but then again, all this is conjecture, some seats just dont work for a given person, or the layout of the bike can be off a bit, or a slight adjustment of seat can make a world of diff....and on and on.
