For me personally, to try being so precise with your pedaling is a waste of time. What you need to work on is what sound you producing. What kind of sound you produce, and the ability to have that sound with your pedaling technique. Because to tell you the truth, you practice at home and then you say to yourself, "okay... this passage need 22/30 pedaling ... okay, get it!" .... then you go to your recital hall .... and you apply your precise 22/30 pedalling .... you'll be surprised that it sounded different. First, the piano is different ... and then, the acoustic of the room and the hall is so much different.
So that's my opinion =) .....
