[HMM I OFF TOURNAMENT] "Company"

What's with you guys acting like kids?!
I understand that the victory date fell within 1-3-4 months/weeks/days (that's 25 days), but since the stage started on the 3rd day of the first week, 1-1-3, the result is 23 days.

I'm not quite following... :confused:
So, is it 18 or 23 days?
Let's start counting:
start: 1-1-3 (0 days)
start of the next week: 1-2-1 (5 days)
start of the next week: 1-3-1 (5 days + 7 days = 12 days)
end: 1-3-4 (12 days + 4 days = 16 days)

I'm completely confused... :o
