Parabellum-
I will agree 100% that it is farther to push, and doesnt seem like the right motion, but when you get it (or even fairly close, as I still dont feel completely solid on my form yet) I think you will notice a major difference.
A few pointers I might give to you(take them for what they are worth):
Form=Try and set up with the balls of your feet below your ass under the bench. I thought this would take away from my balance and stability, but everything else is so frickin tight(If done correctly) that there is no much sway. I actually picked this up the weekend before I went to Naz from MJayM. He has INCREDIBLE technique and form. When my form can match his I will be assured of at least another 50lbs on my bench. The other thing I might mention on your setup is getting set up higher on your traps. BigWhitey was pushing my shoulder blades back down UNDER me when I would get set up. I actually had bruises on the TOPS of my traps from setting up this way. The closest way I can think to tell you to set up, is only your nuts and the top of your traps should be touching the bench.
PRESS MOTION= I couldnt tell much about how you were tucking the elbows, but let me suggest pushing the bar from your belly to over your face in a 45 degree angle, and flair your elbows at around the half way to three-quarter position.
Anyway, don't think Im acting like a know-it-all, just trying to pass along what I picked up from MM.
Lemme know if I can fill in any other blanks for you.
