Personally I've never gone for any ratios. They can hinder your gains. Just go for your max and that's it. If you have it in your mind that you need to do say double the weight in deadlifts that you do in bench, you may be cheating yourself out of doing more. Try to add 5lbs to your lift every week or two until you hit a plateau....then change up your workout routine and do it again.

Wild Bill would be the man to talk to though for actual scientific training percentages. Wait for him to chime in.
