I dunno about this one but i have used a link that listed public event by time (give or take 5 min) and also gave the frequency (Chance of Happening) being High, Med, Low. I have found this to be quite accurate. And the post about the extra enemies spawning and a big battle taking place is correct sometimes the public event is replaced with a huge battle. Yea what the other guy said. He put much better than my attempt but the fact is the same its a guide and its correct. Oh and yea im on xbox360
