In Breaking Bad S05E02, "Madrigal", Lydia shows Mike a list of 11 people who are on Gus's payroll. Including Mike, this would make 12 people on Gus's payroll.
Only, wouldn't it actually be 15?
In the season four finale, "Face Off", Walt murders 3 of Gus's men:
the first one, Tyrus, is killed when Walt has Hector Salamanca detonate a bomb intended to kill Gus.
the second and third man are shot down by Walt when Walt goes to release Jessie from captivity in the lab.
Shouldn't it be 15 men on Gus's payroll and not 12?
It is possible that Gus would choose not to pay the families of any of the men who had died but the show, as far as I am aware, does not establish this one way or another.
Is this a plot hole, am I missing something, or does the show just not provide enough information to make an assessment one way or another?
