104 regions - 3 killer neutrals and i neutral on Tokarara + 8 neutrals in front of each tribe = 92 regions.
Why the neutral in front of tribes?
To stop quick elimination of each player's tribe...it is a condition that you must hold your tribe otherwise you will be eliminated.
What value should this be?
Well to start, i have set this at 7 neutrals on Version 8...but that can be adjusted if thought to be too high.
I have done a count of the regions directly between each tribe around the board.
Jiwiki <-> Chimbu = 6
Chimbu <-> Enga = 7
Enga <-> Highland = 5
Highland <-> Asaro = 7
Asaro <-> Hulli = 7
Hulli <-> Iwan = 8
Iwan <-> Motu = 9
Motu <-> Jiwiki = 8
Here is the Probability stakes

Version 8 showing neutrals in front of tribes set at 7
+ a couple of toned down colours
+ moved the Iwan Tribe to arrive in Kila Kila (makes the distance between Iwan and Hulli larger)
