Quote:Umm...their relative mobility advantage is identical.
4-3 is one.
2-1 is one.
If you move away at speed 4, and I only move speed 3, you will gain one hex a turn of separation.
If you move away at speed 2 and I only move speed one...you will also gain one hex a turn of separation.
3 is 75% of 4, 1 is 50% of 2, so there's a difference.
Let's say you move for 10 turns.
Case 1) Infantry moves 30 hexes, motorized infantry 40. The infantry moves 0.75x what the motorized unit moves.
Case 2) Infantry moves 10 hexes, motorized infantry 20. The infantry moves 0.50x what the motorized unit moves.
Note that in case 2 the weather is bad, so it makes less sense for the motorized unit to have an advantage.
The separation per turn might be the same, the relative difference in how much a unit can move isn't.
