CSI calculation in pool math

[Fingaling]

Wondering if the CSI calculation in the pool math app is correct?

When I use the old pool pal app or the online pool calculator, I get a much better CSI with identical numbers

There is a data point having an issue some where. Go to your Logs and look.

The web based PoolMath is showing CSI of -0.07

Do you have metric or US units selected in the app. Watch the temperature as I think there is an issue of Celsius vs Fahrenheit.

F,

I ran your numbers using a different app altogether and only get .66 if I'm using C degrees... Using F degrees I get -.07 like Marty..

Interesting idea about the units.

When I put in 85 farenheit I get the numbers I showed you. I swapped it to Celsius and put in 29 and got .07

I think the app isnt actually changing the units for some reason as putting in 85 Celsius gives me the same 0.66 as 85 farenheit.


Wish I had tried the different apps before I added all that acid...
