Monster Respawn Rate

I dusted off my Playstation 2 a few weeks back and started up a new game in Final Fantasy XII. Sessions have been short, mostly grinding in the beginning because I am a huge jerk, but what is the respawn rate for monsters in this game? Narrative-wise, I have not gone to the new consul's feast, so I mean really super early, but like Quina at a smorgasbord, I can devour everything in the Estersand with exception to the Wild Saurian. So, cool, I can grind and get lots of LP, but what I want to do is build a sizeable chain for more loot drops. Is this really feasible or should I just wait until I can explore other areas?
