For some reason NA text is different than EU text even though it's the same language. When language was tested way back when, it was done in Europe, so we just accepted that Spanish was faster. Unfortunately NA Spanish was different than EU Spanish, and we never did the testing ourselves. It also turns out that PAL Spanish is 10 seconds faster than NTSC English. Also keep in mind that French is slower everywhere. Here is a spreadsheet with my testing, as well as instructions for how I measured text for each cutscene.
