5 hours/day is a lot...I'm no expert but I would suggest you to understand your weaknesses and focus on them.

! u0 Q2 J" X  `  bIf you're simply unfamiliar with the piece then you just need to do more background work/music studies, for example musical form and modulation etc.  In this way you may pick up the music quicker, this is especially important for more complex and huge works.  Again not many people find it pleasant but it will pay off in the long run.! x' ^5 C9 Z9 s4 E/ G( H9 ?/ G3 u' |

I guess it is just important to stay focused and be patient.  Make sure you're well prepared with a clear mind during your practices, do not practice when you do not want to e.g. when you're very exhausted from work.  It is extremely inefficient and you may find yourself better of holding off the practice till the next day.
