Hi,
Note the 2nd bleach calc proportions do not increase with the gallons-
16000 gal., 10% strength, increase 1.5, add 3 Cup 7 oz.
16500 gal., 10% strength, increase 1.5, add 3 Cup 0 oz.
17000 gal., 10% strength, increase 1.5, add 4 Cup 1 oz.
I repeated the 1.5 series with 6% strength and proportions seemed fine.
I repeated the series at 2.5 increase and proportions seemed fine.
It is possibly a minor error in a data table, and a minor error by any means. But I would recommend checking a similar series for your particular situation to confirm dosage levels. That particular error is off by 25%.
