This was my Jan 2 DC. I ended up going 2 north, as seen below.
Things against going 2 west
In going 2 west I had about a 33% chance to get a 1
and 2 in rack 8, and about 80% (rough guess) to get a 1
or 2 in rack 9. So in my head I had it at 25% + to get screwed with 2 west.. (Note, as arjun pointed out, the problem was a 1
and 2 in both racks 8
and 9. I had incorrectly projected that a 1
or a 2 in rack 9 would be a problem). So, I think a more accurate number was 11%. ( .33 x .33), not approx 25%.
Things against going 2 east
I would have a 16% chance of getting no twos in the remaining two racks. That was the only major downfall I could see
So, I saw the edge in favour of putting the 2 north. But, I did so with a wrong assessment of the rack 9 problem which led me to a wrong percentage.
Anyway, after seeing the mixed feedback I am not sure what the correct answer is. I tend to think I went wrong here as Donk. Derwi, lilrascal and arjun liked 2 west, and Aicirt (mrgibson) liked 2 north, and I think gabe liked my path first, but then thought maybe 2 west was better.
it was neat seeing people’s takes on this one.
