Mash liquor vs. total liquor

[PeterB]

Hello fellow wise brewers...

As a newbie gain brewer, are there any compelling arguments for CRS treatment of the total liquor as opposed to just the mash liquor ??

Many thanks for any light you can shed on this.

Thanks for the prompt reply Chris - your point is taken for sparging liquor. But what about boil top-up & OG adjustment water ??

Thanks
