Question about dilution

I have a question about step 3 in the dilution. It says "Step 3. In about 1 - 2 hours (depending on your system) you should be voiding â??clearâ?? urine about every 15 - 20 minutes. Continue to drink 3-4 oz. more water to replace what you've voided every 20-30 minutes." My question is Does that mean add 3 to 4 ounces of water to the original 8 ounces you were drinking?

I understood it as "after 1-2 hours, stop with the 8 ozs, and only drink enough to equal the amount you piss out."

Step 2 says to only drink 8 oz every fifteen mins for 1 hour, totaling 6 glasses (4 plus the original 2).

hopefully I interpreted that correctly, after looking at it again, its easy to see how it could be interpreted differently.
