Mandelin Test Question

[LoksterEbKDeak]

(Mandelin) The test went right to purple then black. But after about a minute or so it started turning green. Im wondering if only the initial reaction counts or if I should be waiting to see any further changes???

Extreme Test Results:
Marquis: 15 Seconds to Dark purple/Black
Simons: went to a very!!! light purple. Hardly Noticable
Robadope: Light Reddish Brown


Can someone help me interpret these. (My first time ever testing)

Thanks!
