Virtual Supply Truck vs Explicit Supply(FWWC)

[BigDuke66]

Hi
I was wondering how much the Explicit supply rule changes the gameplay. Obviously with the extra units it can lead to more traffic on the roads what could cause problems. But besides that the mechanics how both work regarding the Low Ammo effect may impact the gameplay too, page 76 on the user manual states that:
"In addition, the basic test to determine when Low
Ammo and Low Fuel potentially occurs is modified
by using a default Local Supply Value of 80. This
means that under Explicit Supply, a unit has a 20%
chance of requiring resupply each time the test is
performed."

When I understand correctly, without Explicit supply the local supply value is used to determine if Low Ammo occurs and the local supply value depends on the distance to the supply sources.

Doesn't this overall mean that using the Explicit supply rule will lead to:
A. Units close to a supply source being more often on Low Ammo than it would happen without the Explicit supply rule.
B. Units far away a supply source being less often on Low Ammo than it would happen without the Explicit supply rule.

If so it seems to me that the Explicit supply rule evens the field and makes the probability of a unit going Low Ammo the same no matter how far away it is from a supply source, so the performance would not degrade if moving away from the supply source.
Without Explicit supply the probability of Low Ammo occurring would steadily rise and with that the initial performance would degrade the higher the distance is to a supply source, isn't this what is wanted especially in the FWWC series?
