Well, these are the appropriate lines from "*_AI_Settings.txt":

Max Ship Size Tonnage From Start 1 Amount := 510
Max Ship Size Tonnage From Start 1 Num Turns := 20
Max Ship Size Tonnage From Start 2 Amount := 610
Max Ship Size Tonnage From Start 2 Num Turns := 40
Max Ship Size Tonnage From Start 3 Amount := 0
Max Ship Size Tonnage From Start 3 Num Turns := 0

I assume the "0" entries in the "Start 3" lines mean unlimited (a standard established in other text files for SEIV).

I don't think you can change the number of start points, but it looks like you can change the turn limits and tonnage sizes...
