Kings Stables

recruit_pool "Marshall of the Templars" 0 0.2 1.1 0 requires factions { jerusalem, }
recruit_pool "Constable of Jerusalem" 0 0.2 1.1 0 requires factions { jerusalem, }

Can you please tell me what the 4 numbers represent after the unit name?

[Caesar Clivus]

1st number = number of units immediately available when the building is constructed.
2nd number = replenishment rate of the recruit pool for this unit
3rd = the maximum number of this unit that will become available
4th = the experience level of the unit when trained.

[Gigantus]

In the above case you can only retrain the unit (special unit) but not recruit a new one (0.9999)
