Great thread, very useful. But, getting to the point, you have a typo in there.
Jirachi (Marine Resort): very hard [B / B23F]
Suicune (Marine Resort): very easy [D / B29F]
Moltres (Marine Resort): very easy [C / B40F]
The floors are all accurate, but they are found in Maze Cave. (and Marine Resort has only 19 floors)
Apparently you did not read how the Pokemon would be listed in the Recruit Dex. There's a format that explains it.
Also, it's listed under Maze Cave already.
