The planes gain ranks at different speeds, depending on their quality. There are 3 qualities: stock planes, Skilled planes and Named Squad planes. Think of it as Common, Rare and Unique.

While a Tenzan Murata may go from lowest rank to double chevron in a few runs (pretty much gaining one rank per battle if no plane is lost in the slot), a Type 97/99 bomber will take at least 3 times as many battles (being optimistic here) to get from lowest rank to double chevron.

When I made my M52C Skilled fighters through the conversion quests, I wrote on paper the number of 1-1 battles needed to double chevron each plane required. It was a couple months ago, that paper somehow got lost. I have some more Skilled Pilots thingies, and thins event showed me how useful are those fighters, so I'm gonna make more.
