SOASE Fleet Supply

So, I've recently started playing SOASE again, and am playing the Rebelllion Mod, "Distant Stars".

The Fleet Supply is set at (max) 4000. I want to reduce that back to the default of 2000, 0r even 1000 due to massive lag when playing all Rebellion factions at once.

I've tried this:

 fleetSupplyData-Small
  fleetSupplyScalar 0.25
 fleetSupplyData-Normal
  fleetSupplyScalar 0.50
 fleetSupplyData-Large
  fleetSupplyScalar 1.00

in the GameInfo folder of the Mod, and also in the Rebellion folder itself, with no change appearing in-game.

Any help in where I'm making a mistake will be very much appreciated

Thanx!
