I think that's the gist - the table is confusing and complex even for a French speaker.

"Tourist" cards should always be "you can ride basically everything" and "more expensive than if you know what you're doing". I have no idea what a "day pass" on the Metro is, but tourists will gladly pay more for something they don't have to think about and works everywhere.

I purchased these for my family on my last trip, and it took a little work; I had to go to the office in the train station, then ask, there was confusion with the Navigo vs the Navigo Easy. In the end, it worked, and the $2 cost of the card was covered by the discount on the 10-ride pack.

That said, the just-use-your-credit card system in London is way better.
