Sure, but the article doesn't support your opinion then. The article refers to a single continuous WC, not a daily consecutive WC.

For a daily consecutive WC of 1% per day for 30 days you will have 26% new SW in the tank. For a weekly consecutive WC of 10% weekly for 30 days you will have 34% new SW in the tank. If you change those WC numbers to 2% and 20% you will change 45% and 60% over 30 days respectively.
