Empirical estimates of percentiles, with upper confidence limits, for three percentiles of variability and four formulation categories

Formulation category	Dilution/concentrate	Sample size	Quantile 95%	Upper bound 95% CI	Quantile 97.5%	Upper bound 95% CI	Quantile 99%	Upper bound 95% CI
Organic solvent	Concentrate	1,153	18	20	24	30	32	44
Water based	Concentrate	1,073	8	10	16	21	28	41
Solid	Concentrate	471	8	11	11	14	14	17
Other	Concentrate	131	20	NA	65	NA	84	NA
Organic solvent	Dilution	1,553	49	55	64	67	73	80
Water based	Dilution	1,567	40	44	55	60	69	75
Solid	Dilution	710	51	57	63	72	74	102
Other	Dilution	105	56	61	58	NA	61	NA

CI: confidence interval; NA: situations in which there was insufficient data to obtain an upper confidence limit.
