I started out last Fathers day back ridng . Because of my weight my LBS who has been around since 1946 told me to keep my tires at max pressure ! I have on all 3 of my bikes and NO bent rims and NO pinch flats . My starting weight was 371 lbs . Take out of this what you will . I check my presure befor every ride and never let it run low and actually I keep it a couple pounds over . my weight now is 243 .

People might top them up every day (or in my case, once every couple weeks). They don't pump them up from flat every day!! I pump mine to somewhere between 90 and 100 psi ... and a couple weeks later when I check, they're down to maybe 75-80 psi, so I top them back up to somewhere between 90 and 100 psi.
By flat, do you mean flat? As in ... no air? Or do you mean ... ever-so-slightly squishier than the were a couple days ago?
If your tires are going completely flat every day, there's a problem. If I were you I'd very carefully change the tubes and tires.

From what I hear from people is that maybe I dont need 120, but from 90 (the pdf) to 110 (recommended by sheldon).

I dont get a flat everyday, I just mean that I release the pressure and repump them to make sure pressure stays at 120ish. This is what my LBS told me to do, I dont have a leak but what they told me is that at that pressure the tubes will just bleed some air due to the high pressure.

Try filling your tires to 110 and just leaving them for a week or two and see what happens. But give them a squeeze just before your rides to make sure they aren't too low.
