Protein Shake Question...?

So I am drinking
protein shakes made with mass xxx from GNC, and I usually just use what is
called "one jumbo scoop" or 1/2 scoop into a glass of milk, even though it
recommends for every scoop you use 3 glasses of milk, will that have any
difference in the digestion or processing of the shake - if i only have 1 glass
of milk for a scoop instead of 3?
it won't matter but thats less muscle building power...
