LOL. I tend to go for the middle distance. (See Valkyrie Profile. xD )
I also did similar in Dragon Warrior VII's Monster Park, its an optional sidequest, but man, does it really complete the whole damn game.
But yeah, I find myself saving time by reading a BUNNNNNCH before I dive into a rpg. I find it easier to plan ahead classes, purchases, and when to AND NOT to take quests. Mostly to minimize my time or/and need to either power-level or equip my party correctly. See I used to be a marathon runner until I realized how huge my backlog was and decided to fuck all and "to finish" some damn games.
I couldn't be arsed to miss out on some great game because I'm backlogged with these rpgs (that are ALSO great too). Like for an example, lets say I finally get around to play Valkyria Chronicles but then The Last Guardian is released. Oh yeah, I put that off for those short games and their awesome experience.
Only during gaming's serious seasonal downtimes I'd tend to play some rpgs. That I had noticed.
The last game I somewhat did a marathon in was Opoona, its enjoyable to run about in.

There's no guide or a FAQ for this when it first released and I found the experience in playing this very memorable. I try to push myself to enjoy more rpgs this way. I'd do so early on, and if its turning completely left field (boring) I'd go for the middle distance.
Also, Valkyrie Profile I had replayed several times, hence the middle distance, not because it was boring.
Jam it back in, in the dark.
