I'm sorry, but I don't quite understand your question.
In reading the posts that followed this one I see you have gotten a lot of really good advice from other brewers. I hope those answered your concerns.
In short, you loose water volume during brewing three ways:
1. Grain absorbs some of the water
2. Boil-off will take some of your pre-boil water.
3. Hops/trub losses
Again, the larger the batch volume, the less impact a small miscalculation will have. And as mentioned in another post, it is ideal if you hit your original gravity with exactly the right amount of wort in the fermenter bucket (I usually want about 5.5 gal. in the fermenter for a 5 gal batch). But if you come up short or long on volume, if the gravity is OK then just let it ride. The beer will probably taste OK even if it isn't perfect. If the gravity is way over, you can probably add a little distilled or boiled water to top it off. If the gravity is low and the volume is off, well, all I can suggest is a trip to the dump and try again. Sorry.
The key here is to hit your gravity reading. If that is right, then it is a pretty good indicator that the rest of the process is OK.
Hope this is of some help.
