An example first:
You have one HQ with two motorized units attached.
The HQ is 5 hexes and 5 MP from railhead.
Both motorized are 3 MP and 3 hexes from the HQ, and they are, in fact, in the same hex.
One unit, we'll call it MU1, has a morale of 95.
The other, MU2, has a morale of 75.
In this sort of case, I would expect that MU1 would receive more fuel and achieve more MP at turn start than MU2.
Even despite supply distances, unit status itself (experience, fatigue, morale, and percentage of vehicles) will cause variation even when two units under one HQ are in the same hex.
I'm surprised to hear Elmo say that it does not matter whether your subordinate units are 3 hexes/15 MPs from the parent HQ or 1 hex/1 MP. Frankly, I don't believe Elmo is precise in saying so, because I've never, ever seen two units under 1 HQ that share a hex together receive the same amount of supply. But, he may be speaking completely truthfully and my point about morale/experience/fatigue may be the whole explanation for the MP differences.
