LIGHTLY Diluting???

I have been reading these boards for a short bit and have often heard some say to LIGHTLY dilute. What is the difference of the regular form of diluting and lightly diluting? I would "assume" that it means less water and/or sports drinks....but how much less is it? Also, are there other differences?

Some people drink buckets of water days before a piss test. That does no good except get you a negetive dillute test day. Just drink 48 ounces of water or preferably gatorade the morning of the test to help dillute the sample so you can pass.
