-the units move speed,the guns muzzle velocity,the weapon ranges,the units range are all proportional to each other!
So there is no cheat no shit!But to make gameplay better and to fit the SuStr engine i had to made some small decisions:
*all units move with their max speed except the aircrafts (ex.: Panzerkampfwagen III Ausf. A is moving with 32 km/h;the infantry is running with speed of 20 km/h) ->becouse they were very slow with the On- Off-Road average speed
*I'm using the off-road range for all units (ex.: Panzerkampfwagen III Ausf. A's range is 95 km which means that this unit can cross an 512x512 map 18x

*Now the biggest map (realistic map proportional to weapon ranges,unit ranges,speed and muzzle velocity)is an 5,24x5,24 km map which is the 512x512 map.
There is a "changelog" about the project in "All about PRM" topic,have a look at it.
