That's not rules. The translated DB1 says the same thing on all translations, the stats cover current battles/performance for each character. Itachi's stats cover his sick state, not any other state. Jiraiyas stats cover his battle with Pain, of course the stats are tiered, and don't cover transformations or anything so those were Jiraiyas base stats in that battle.
