Can somebody explain these two in the Unit Information Panel?

What formula is used in the Kills/casualties ratio?

What does "destroyed by" mean? If this unit was destroyed you wouldn't ever get to see this panel anyway, would you?

Well, you can actually bring back killed units.

When you lost for example one infantry and want to buy another the game asks you if you want to revive the destroyed one. A reformed unit costs the same as a new of the same type, but keeps a bit of XP of the lost one.

Oh I get the "destroyed by" now - thanks bebro.

What about the "Kills/Casualties ratio" formula though? Anybody know? By looking at the picture above it it appears that the formula would be 11/29 but that comes to .379, not 61.5.
