Batch Size
Size of the batch the recipe calls for and represents the final volume of beer you intend to achieve. As an example, you receive a recipe that calls for a final volume of 5 Gallons. Thus, 5 Gallons is your batch size.
Note also that the Batch size should NOT be used as a "pre-boil" designation. The pre-boil calculator will determine for you what the pre-boil size should be before boiling and evaporation losses. For details on how pre-boil amounts are calculated see the Pre-Boil Calculator.

No that quote is correct dicko.
It just does not mention that the final wort size you aim to achieve is the volume at the end of the boil not the volume you get in the fermentor.
It makes sense that the wort size for all your calculations should be the size at the end of the boil not what you collect into the fermentor
other wise everything will be out ie if you use 20litres as batch size(thinking thats what you want in the fermentor) for your calcs but in fact at the end of boil you have 25litres which means all colour IBU and gravity calcs should be for the actuall size of the wort at the end of the boil not what you get into the fermentor.
So when you read in the help menu "the final volume you intend to achieve" this means the volume at the end of the boil not the volume you want to acheive in the fermentor.
The volume you get in the fermentor means nothing its up to your system how much you collect from the kettle. What matters is the size of the wort at the end of boil.
So basiclly although the help menu quote may confuse some by not mentioning that, it is certainlly correct. You always think of the final volume of wort you set out to make is the volume at the end of the boil.
does that make sense?
simply the batch size in the recipe does not take into account any loses so you set batch size as the volume of wort you need at the end of boil not what you are aiming to get into the fermentor.
So with the water needed calculator you work out how much wort you lose to your system then add the amount of wort you want in the fermentor both together and that gives you your batch size.
Anyone still confused?
