Fun with math no doubt.
I looked at two of the closest dates available with a decent spread: (3-24) Z154193 and (4-28) Z163961. That is either 34 or 36 days (34 if you consider Z154193 was built at the end of the day and Z163961 was built at the beginning of the day). Using those numbers, the average is 287 trucks a day. 287 x 24 (March 1 to Mach 24) = 6888 trucks. Backing up from 3-24, the earliest for March would be Z147305.

Certainly Z146839 was built in either February or March. I'll add an asterisk, ? for the month and a note. Ill bet we can make better estimates soon.
