the global index is indicating "uitstekend" (excellent), which is correct, but this means that all 4 subindexes (for the 4 pollutants) should also be "excellent". This is not (always) the case, see screenshots. This is probably due to wrong subindex scales being used (24h/max8) and not the hourly subindex scales (?).
