Forts and oasis

What is the method used to work out how many forts and oasis u can have at each lvl. I thought it was 'Oasis are half ur lvl/title rounded up and Forts are a 1/4 of ur lvl/title rounded up'

lvl 1 is 1 oasis...and i dont think u could farm a fort at lvl 1

Oasis = Your general title lvl / 2 (rounded up)
Forts/Sub cities = 1 per title name. Ex. Baron - 1, Viscount - 2, Earl - 3, Marquis - 4, Duke - 5 etc...

No need to do the math every level. You get a new oasis slot every 2 levels, a new fort slot every 3 levels, and a new city every 3 levels.

Thanks. I'm lvl 11 so I can have 3 forts and 5 or 6 oasis
