TF100 test instructions error

[Wildcat]

When doing the FC test my test card instructions says to multiply the number of drops by .05 which at 24 drops means my FC is 1.2. The Instructions in the sticky in this forum calls for multiplying by .5 which makes more sense, my FC is 12. Could confuse someone who is just using th eczrd and is unfamiliar with what the range of results for their pool is. With my high CYA And a FC of 1.2 I would be adding gallons of bleach!

Really? Mine says to multiply by 0.5. I honestly wonder why the instructions don't say to divide by 2. That makes much more sense to my brain. when I was first testing I used my calculator to do the multiplication and when I saw the results I was like..."Oh, duh!"

mine too says .05...The next line right after says .5, so I just double checked online and saw that it was indeed .5

Ditto. I also prefer to just divide by 2.

I should have been more clear, the first mention says .5 but the example shows .05
