Just curious about the chemistry. Usually once I begin to add R-0009 I notice some stringy precipitates form. What are those, exactly? Thank you.
What are the precipitates during TA test?

I have never seen that before. The R-0009 is simply sulfuric acid that consumes alkalinity and eventually shifts the pH of the sample below 4.5 which is the green/red transition point.
Is your R-0008 indicator dye old? It can go bad with age, get clumpy and start clinging to the inside of the dropper bottle.
Other than a possibly compromised indicator reagent, I have never seen what you describe.
