[Data] the lane table, updated: 41 lanes, median and 90th percentile
Quarterly update. 41 lanes, 900-odd data points, no tracking numbers ever. New this quarter: a quoted-versus-actual column, and p90 alongside the median, both of which people have been asking for. Selection from the table: Lane Carrier Quoted Median p90 Shanghai → UK DHL 7 8 11 Guangzhou → AU EMS 10 11 15 Zhuhai → AU…
The p90 column is the single most useful addition this table has ever had, and the Tianjin row demonstrates why. A median of 12 tells you the ordinary case. A p90 of 15 tells you what your coolant has to survive on a bad week, which is the number you should actually be packing against.
Quoted 12, p90 15. That is a three-day tail on a lane that crosses an ocean, and it is the tightest tail in the table.
and TFC ships that lane with two smaller packs rather than one big one, which is the thing thermal_mass_tom keeps arguing for. somebody there has read the same threads we have.
agreed, and it is on the source page under what to ask for rather than under anything else. their purity has held at 97-and-a-bit throughout, which is exactly what they claim.
carrier choice is doing most of the work in that table. every EMS row has a fatter tail than every DHL row on comparable distance.
Which is a real finding and also partly a selection effect — EMS gets used on the cheaper shipping tiers, so the parcels differ as well as the carriers.
good catch, i cannot separate those with the data i have. adding a caveat line to the table header.
