Using 25 ml test, here’s some pictures. I think when I started testing I’d document 80, but now I’d document 90.

Now that's a stirrer...

Looks like 90 to me. That's the color I get. I look for no significant color change between drops.

The method for drops based titration is quite simple.
You add drops one at time until the last drop you add results in NO FURTHER COLOR CHANGE. Subtract that last drop from your total and the result is your end point
