Pool math app liquid chlorine calculations

I’m not sure who to notify so I’ll try here.

The pool math app computes the same free chlorine parts per million for any bleach percentage 11 and above. Ex:

10%, .5 gal = 1.1ppm
11%, .5 gal = 1.4ppm
12-21% all stay 1.4ppm

I found it if I double the volume and half my percentage I’ll get numbers that vary a little.

I have been getting chlorine in bulk 12-15%. Have not tested it’s potency yet.
