How are you testing FC? I haven't seen that degree of testing in an FC test except from pool stores.
Are you performing an OCLT?
If so:
Is the water clear?
Your loss of 1.17 would possibly qualify as 1 or less, but if you are slamming I would continue.
What is your CC?

Do you have an FAS-DPD test?
 
Yes I am testing FC with my PoolLab that uses FAS-DPD tablet reagents. I am not slamming, water is clear. Just wanted to see where my OCL was at. I did not check CC but yesterday it was less than .5.
