Old PoolMath difference from new PoolMath

[calstar]

Slaming my pool, target is 20, FC was @16, old math tells me to add 3qts 3cps, new phone app(iPhone not premium subscription) tells me 2qts 1cp, significant difference. I used the phone app of 2qts 1cp, tested an hour later and reading was right at target FC 20. Anybody else notice differences?

I am getting the same volume of 10% bleach to raise your 15000 gallon pool by 4 ppm FC. 77 oz. Using PoolMath app and webpage.

OK, when using the old PM I didn't add the correct % of bleach, sorry for the confusion and thanks for the help. As you said it is 77oz or 2qts 1cp, same as the phone app.

Change the Bleach concentration to 10%.
