If we spread the stress out over 3 days, the trainee is now accumulating stress over two separate bouts and the adaptation cycle is now up to 4 or 5 days. In other words, they aren't providing a stress, recovering, and adapting inside of 48 hours. There is also some concern that the 3 sets could be almost enough to stimulate an adaptation response but not quite. Let's say we get 90% of the way there. The trainee now rests for 48 hours which recovers this down to say 20%. On overhead day, then add another set of bench which puts them to say 90% again. This is kind of the problem. Hopefully it makes some kind of sense.
I guess the gist of it is that this approach is moving more towards a weekly programming methodology which complicates things when we could just do four sets. However, you are onto something which is that Starting Strength only benches/presses 1.5 per week each on average which will eventually be insufficient. This is why Andy Baker recommends pressing and benching twice a week each sooner than you think is necessary. Of course, this requires that the trainee really understands how to tinker with intensity and volume to get this right. I need coffee. Too early for this long of post.
