CC testing, 0.x vs 0.0x vs trace

[doc8404]

New to this and loving the site. So I test for FC, then do the CC test. ALWAYS turns the slightest shade of pink and one drop returns it to clear.

So by the instructions, that is 0.5

1) is it really? I always say "trace" as I doubt it is 0.5

2) is it worth diluting to be more accurate?

FC levels are always steady and no issues.

Not worth diluting to get more granular, I only test for cc if i think there might be some say after a pool party / high bather load. If you are diligently using a cover you may get a little and I mean less than .5 but nothing to be concerned about. Save your reagents and only test for it if you think there is a reason like an unusual quick amount of FC loss.
