Nominal is the nominal(or desired) amount of this item spawned
restock defines the time in seconds it takes to restock the item if min is reached, setting it to a lower number will make the item spawn faster
min ist the minium amount found on the map, after that it will trigger the restock timer to get back to the nominal value
the flags you mentioned just tell the game which items it should count towards this nominal. So if you set any of them to 1 its going to reduce the spawnrate. means it counts all of x item in
cargo(inventories of cars/bags)
hoarders(inventories of tents or containers)
on map(which should be the only one set to 1)
player(self explanatory)
