I think i know why my FC was so low....
I got the pump running at 430pm....then put the bleach in after making sure that the pump was running fine.
I realized later that my skimmer wasnt really working, then saw that my waterline was above the top 2 screws...so I did a rookie mistake and backwashed until the waterline was about mid-way of the skimmer box. Skimmer is now happy and working great....
Around 530 or so, I started to clean the pool, that is, with the brush and really gave the pool a good scrubbing. The clear water, that it was, became murky and cloudy. Having large aquariums I knew this to be normal after cleaning it so I didnt think anything of it.
I think between the 4-5 inches of water I purged plus striring the pot if you will, caused my FC to plummet.
Since my wife is out of town till tomorrow, and to make sure I have a nice jump on things, I put in 242 more oz of bleach. With my existing 2.5 plus according to poolmath, this would add 6.6 for a total of 9.1 FC..or so I thought
Here are my new results:
FC - 13...I think I inadvertantly shocked my pool XD
CC - .5
TC - 13.5
TA - 100
CYA - waiting to check in a week or so
It is currently raining lightly, so I somewhat expect these results to go a little outta whack. Rain is expected for Sunday also. I wonder if I should make any adjustments for the next 24-48hrs aside from testing.
