Colours make multiplier ranges easier to read. They label historical observations, not signals for the next round.
Three multiplier ranges
Blue is below 2.00x; purple is from 2.00x to below 10.00x; pink is 10.00x or higher. Read the numeric multiplier for the precise value.
A gap is not a multiplier
Missing or interrupted data must be shown separately, not as 0x, 1x or any invented round. Unconnected sources and genuine zero values must also remain distinct.
Check sources and timestamps first
When comparing windows or platforms, check the source, latest round time and valid sample. Matching colours imply neither matching data quality nor future performance.
