I ve only been Oly lifting for a while and this is just my personal opinion:
I'm not so sure about the loading and % used...that probably will burn you out unless everything form nutrition to sleep etc is spot on.
There is something to be said for just using the lifts though: it is easy to get stuck on certain technical aspects and certain exercises and it can be quite good to sometimes 'just get on with it'. having said that, i've just completed 2 weeks of pulls of the blocks and power versions of the lifts to get the 2nd pull right! (could you tell i m a novice?! ;-p)
i've found this to be true in other areas as well: when i learn a new technique in judo or jitsu it can be really beneficial to just do the whole thing in one go over and over again rather than to break it down into smaller parts!
i supose it s quite hard to assess this without a coach...
