Number of Turns per World (Little Upsilon)

I know this is hidden deep in the gamenews or forums, but my eyes hurt...

What are the current number of gamemonths per real-day per world?

I know LU is 6
Documentation says FB is 3, but I'm certain it's 6 also
And I believe WG is 4(?)

Does anyone know what all five worlds are for certain?
Many thanks in advance!

I believe they are as follows

LU-6
FB-6
KB-6
WG-4
GR-4
