Thanks! I'm really happy with those tables. I'm currently working on doing sets of distinct tables for each character so I'm happy to hear that they're a hit so far. I've had some good feedback about them in person from the little bit of play testing I've done so far.
In regards to the Major Arcana: Yes. Currently, they are treated the same as other cards in regards to judging success by numerical value although I had been playing with a slightly altered ruleset that would see this change. It would sort of simplify the situation making the resolutions even faster and it would also introduce a bell curve with partial successes. More on that later!
