I'm all for finding out the nuts and bolts of how the map works, I'm not sure that having people follow a pre-determined strategy can benefit the town over scum (eg anytime scum know where to find town it makes their job easier).
If a strategy for placement comes into discussion later that is obvious, brilliant and definitely works in favor of the Town I will change my opinion, otherwise I feel a maximum spread strategy may confuse more than help.
This is due to the connectedness of the map. A max spread would still give scum access to 3-5 people depending on the area.
Breaking up into groups where the scum can't move would help, if there were no pro-town power roles (eg agreeing to stay in only areas 1,4,7 and 8 as they are not connected to each other and scum couldn't move to any other group as they would be 2 moves away).
This is why I'm not convinced on a strategy for where people go for the night, other than being in areas 4 or 6 gives you the most areas to move to/from (good for scum, bad for town).
Also, EM - reasons for FOS?
