Bromine Chemistry Question

[FormerBromineUser]

I have a bunch of questions about all that but for now I need to get back to the TA issue...
Here's what I did. I added 3/4G of MA, waited 4 hours, got a pH of 7.1ish and added 1 more quart of MA (and 3/4C of diclor). After an hour, I turned on my 2 fountains and the step swirling jets and then went to bed. In the morning my results were:
pH 7.4
FC 3.6
CC 0.6
TA 200, then 180, then 200
CH 90
I freaked out and took a sample into Leslie's.
They agreed with the pH but they said TA was 150, yesterday afternoon they had 170 so they think the acid and aeration is working. But, I returned home to retest TA and I got 200 again. I don't know who is right or wrong on these numbers. I even purchased fresh TA reagents the other day because my numbers weren't agreeing. I will continue with lowering my TA per directions but I don't know which numbers to trust here. I'm thinking Leslie's as I had TA at 200 before the gallon of acid and I still have TA of 200 and the acid MUST have done something....!
