Safety
There are several encounter tables in a given area, each with its own encounters; you have a chance to fight an encounter of any given type, and this chance can be modified by certain materia; if no special encounter type is chosen, a Normal Battle will be fought; note that while this usually matches the encounter type, there are exceptions to this rule (e.g., a Back Attack in a Normal Battle slot or vice-versa); Chocobo Lure battles are only fought while on chocobo tracks with a Chocobo Lure materia equipped; only one Mystery Ninja encounter is available at any given time, based on the party's level, and only if Yuffie has not joined the party
Slot Type
How common this encounter is for its slot type; each encounter is out of 256; for Chocobo Lure encounters, these values are for a Meet Chocobos value of 8, and increase proportionally for higher values to a maximum of ×4 at Meet Chocobos 32

The rate of Steal success per item by a character of equal level to the monster; these rates will change based on the level difference between the Stealing character and the monster; hover over a percentage to see the base rate (which is based on being 10 levels higher than the monster); this rate is multiplied by 80%±2% per level difference; only one item can be stolen, so an increase in level may in some cases decrease the effective Steal rate of items later in the list
