A shared map becomes more useful when contributors follow the same simple routine. Consistent sampling does not turn a community test into a laboratory analysis, but it does make observations easier to compare.
Keep the method repeatable
Use the same sample volume, the specified number of reagent drops and the full waiting time. Photograph the tube under neutral light and record whether the surface was cleaned during the previous 24 hours.
Context matters
A result without context is difficult to interpret. Environment type, location, surface condition and timing help other contributors understand what they are seeing.
Document, do not overstate
Chemtrail Tracker is designed to collect observations. Individual color results should be described accurately and without conclusions that the test cannot establish.
