Did you get this info from the manual? Have you flown the C-172 and how many hours do have in it?
Pilot manuals are basically guides on what a plane will do, I cant remember when a manual came close to what the plane actually does in real life.
Let me ask you this does a C-172 fly with full flaps extended Yes or No? Is Yes how slow does the airplane fly with full flaps down. Does it fly slower with 10 degrees of flaps or 40 degrees ? Have you ever aborted a landing at 2 ft off the ground for a go around with full flaps extended? If yes then why cant you takeoff with full flaps extended? and after liftoff bring up the flaps slowly inground effect accelerate to Vy then climb out. Fly the plane not the manual.
I been instructing for over 30 years in singles, multi's and helicopters. Showing the student all of what the airframe will do and not do, is part of the learning process. As an instructor we have to allow the student to get into a bad position to show what not to do, we also show what you can do other then what the manual says to do. To be a good sound pilot you have to experience all of what the airframe will and will not do.
There have been many a day that I cant get more power out of the engine than what the manual said for a given day, or a better fuel burn at a different power setting than what the books says.
In the days when the airplane first started to fly there were no manuals, aerodynamic therory changed on a daily bases and so did flight training manuals to this day. But when you get behind the controls its a different story. I have flown airplanes and helicopters for the first time without picking up the manual at all.
Im not trying to belittle anybody here, but you would freak, of what my dad and myself have done in a 172 to make it fly out of some of the places we have taken it into.
Have you taken a 172 and shot touch and gos takeoffs over and over again without making a pattern approach just buy staying over the runway center line. In a stong head wind takeoff, climb, drift back and land, takeoff, climb, drift back and land. Theres no manual to tell you how to fly this way.
