First Mr. Frag points to chapter 14.3 of the manual to explain the maximum range:
Old news so far. But this caught my attention:14.3 GROUND UNIT SUPPLY
When tracing a supply path for movement of ground units or overland movement of supplies, a
supply value is generated. This is determined by tracing a path from the base transferring
supplies or the ground unit moving to the destination. This supply value determines whether the
move is legal, and how much of the supplies are used up during the move. The supply value of a
move is calculated by subtracting the following from 100 (900 if a ground unit move):
- 2 for each hex moved along a rail/highway
- 5 for each hex moved along a road
- 25 for each hex moved along a trail
- 50 for each hex moved cross country
... and ...ORIGINAL: Mr.Frag
There are 4 completely separate concepts all rolled into one thing [Chapter 14.3 - VSWG].
(a) Supply flow for units from a base
(b) Supply flow for bases from a base
(c) goods flow for industry (base to base)
(d) unit movement and the effect of enemies in the way.
The math is the same, but the maximum ranges differ.
It is probably the second most complex thing in the game to understand.
(c) is a little special because it is based on a 3 day cycle and the range changes each day of that cycle.
ORIGINAL: Mr.Frag
Nope, when shuffling resources/oil, it cycles through 3 separate ranges.
A long range pull
A medium range pull
A short range pull
Mike could probably explain why it needs to be that way, I just look at it from the standpoint it works. [:D]
Sadly, Mike didn't explain why it needs to be this way, and what this exactly means. Can someone else explain it? I've never heard of this before.
