Combat vs. Drill: The eternal question

[Minor Annoyance]

The color of the line indicates how many first strikes the attacker has versus the defender; if they are even, use the black line.

As for the rest of the graph, the ratio means the ratio of their strengths (attacker:defender).

If you look to the left of the graph, where it's sub-1.0, that means situations where the attacker has less strength than the defender.

At 1.000000001, black line (meaning, 1.0, equal first strikes), it's about 60% chance of attacker victory. At 0.999999999, it's less than 50%. It's exactly 50% if they are equal strength, equal first strikes.

Text says that if both units have equal strength but attacker has Drill 1, odds are 56.8% in its favor. But it's more like 60% if it has Combat 1 instead of Drill 1.

O.K. I think I understand. The graph shows everything above 1.0 and below 1.0, but at exactly 1.0 there would just be a single black dot at 50% because it covers only that point and not a range across other ratios.
