For some of us building lather in a bowl is just part of the experience. Shaving is more than a chore at that point so we don't mind taking the extra time. We're having fun.

Also, my technique is a little different since I'm female. Legs are big and have a lot of surface area to shave. If I try to lather all at once toward the end the quality of the lather starts to drop. I lather a little and shave a little and then lather a little more and shave a little more as I work my way around. I'm more about quality than speed. A bowl is a handy storage place for the lather I haven't used yet.
