One thing i didn't like and it didn't really start here, was saying that Scotty always grossly overestimated the time it would take to fix something when talking to the captain. 'How else can i be a miracle worker'
During TOS i always thought Scotty gave his best estimate.
KIRK
Your timing is excellent, Mr.
Scott. You've fixed the barn door
after the horse has come home.
How much refit time till we can
take her out again?
SCOTTY
Eight weeks, sir.
(as Kirk opens
his mouth)
But you don't have eight weeks so
I'll do it for ya in two.
KIRK
(considers)
Mr. Scott. Have you always
multiplied your repair estimates
by a factor of four?
SCOTTY
Certainly, sir. How else can I
keep my reputation as a miracle
worker?
