Aggregated Gas Storage Inventory – Europe

I looked at the &quot;all&quot; timeline graph for France here [1]. Could someone explain why the big jump ~2012 ?<p>[1] <a href="https:&#x2F;&#x2F;agsi.gie.eu&#x2F;data-overview&#x2F;graphs&#x2F;FR" rel="nofollow">https:&#x2F;&#x2F;agsi.gie.eu&#x2F;data-overview&#x2F;graphs&#x2F;FR</a>

Germany: stored 239.64, consumption per year 905.30 ⇒ 239×12&#x2F;903 ≃ 3.17 months<p>Spain: stored 32.99, consumption per year 338.99 ⇒ 32×12&#x2F;338 ≃ 1.17 months<p>However, the “Stock&#x2F;Cons” column, annotated with “Filling level compared to annual consumption”, shows this:<p>Germany: 26.47 ⇒ 26.47×12 ≃ 317.64 months<p>Spain: 9.73 ⇒ 9.73×12 ≃ 116.76 months<p>What did I misunderstand?

Does anyone know what the consumption number refers to? Daily? Weekly? Yearly?
