Emerald Spire level progression?

[Bioboygamer]

I'm running an Emerald Spire campaign, but my players are bad with keeping track of experience. As such, I've abstracted it, and simply informed them of when they level up.

However, this means that I am uncertain about what level they should be at any given floor.

Is it possible for someone to let me know what level the party should be at for each floor of the Emerald Spire?

The party size varies, but is generally no less than three players and no more than seven.

They are currently at the start of the fifth floor, and are level 4.

I've run the Spire from Level 1 to level 14 (they just discovered there's a level 15!) for a party of 5. They have followed the progression Cpt Kirstov identified; however that was only after a large number of "side" adventures in the Echo Woods (the Thornkeep Sourcebook has been very useful for that). The stated progression is for four PCs, so with 5 PCs they would be lower level but for their side adventures. As this could have proven lethal several times, I'm fine with it.

With the varying number of players, it can be hard to pin down the exact number. Seven PCs of that level will easily overcome challenges that would be brutal for 3 PCs - especially on certain levels.

I would recommend following that progression listed above, but modifying the encounters. For 3 PCs, perhaps have a regular NPC adventurer from Fort Inevitable who is willing to tag along. For 6-7 pcs, buff out the encounters with some extra creatures. In the Drowned Level, for instance, it's easy to justify the presence of a shark or an extra Imp.
