Okay the instructions clearly say drop one drop at a time swirling between each and that has been what I have been doing. On tests that yield a high number of drops and you have a track record of the test results is it okay to add multiple drops in the beginning until you approach the color change threshold or will this affect the test results? Example CA if your value is 300 or so can you add 10 drops twice swirling between each then drop 1 at a time? Or TA if your value is around 100 can you add 5 drops right off the bat then go one at a time?
