K-2006 TA Test Question.

I am curious as this is my first season with the K-2006 setup. The TA test calls for the color to go from Green to Red/Purple. Do I stop when the drops hit the green sample water and turn reddish or do I swirl and drop till the entire sample has turned color.

It seems to take about 2-3 extra drops to get the whole thing red. Pool store is saying my TA is 100 and to get the whole sample red its around 130 by my test.

Can anyone comment on the correct method?

Thanks for any assistance.
