I typically am going for as close to max S.Link as possible so I only go 1 day a month. It's so fun though! I haven't played in a while but I left off at Rise's dungeon and probably spent 10 hours in it? Just doing all the sidequests for Kanji's etc, a lil gold hand farmin'.
I cleared it at level 46 so I am totally overleveled but still. I love how the battle system is actually fun. --- SMT IV 2013! BELIEVE!
I probably go in the TV on the first day it becomes available to save someone, then I never go in again until the next investigation. I don't think I spent a particularly long amount of time inside the tv itself though, most of my time is spent finding/fusing persona and doing sidequests, it's ludicrously easy to gain exp because of the gold hands. --- PSN: LostRequiem1 - Feel free to add
I only go on the first day that it's available, do whatever needs to be done there, and spend the rest of the time on Links. --- Blades will bleed. Shields will shatter. But as the light fades, will The Hero rise again? Or will Darkness reign? ~ Zelda TP Trailer 1
I rescue everybody in one day. On rainy days I go back to hunt for hands and kill extra bosses when there are no social links I care about nor any Personas worth drinking coffee with. --- "Once again, ViewtifulGene's logic blows minds and crushes dreams." -TheGamingGolfer "Supez teh king" -dedekong
I go whenever I feel like it. It's easy to complete the dungeon in one day, but then I go in to defeat the bonus boss or do quests. I don't really restrict it to rainy days, which probably hurts my chances at a max SL run, but I really like the dungeon crawling aspect of the game, so I don't care.
