That's exactly the information that I used to 'determine' how to interpret the table. Its not guaranteed of course, but all signs point to the table being the earnings per 10 euro spent. Which is a weird value, and even stranger to not mention it in the T&Cs, but its the only value that makes sense with the advertised earning rates.

I'm very curious how this will work in practice. Especially if a flight or hotel stay doesn't post automatically and retro claim is needed..would you need to do that twice? Would they be synchronised somehow?
