    CYA testing clarification

    When testing for CYA, my TF-100 kit states to mix and "WAIT" 30 seconds, then mix again.

    However, I see posts and videos that state to "MIX" for 30 seconds.

    I have done both methods and I see no difference. I may be splitting hairs here, but is one method the correct method, or does it truly matter?

    I usually shake and then wait 5 minutes and shake again then test.

    The Taylor instructions say to mix for 30 seconds, so that is why videos you see also say that. In my opinion, either works. I shake mine for 30 seconds-ish

    I've done it both ways and it didn't seem to make a difference in my tests. Just curious. Tnx
