Rank of Adventurer
"Basically, all requests have points assigned to them. You rank up by completing them and passing a certain point threshold, but the points themselves are undisclosed data."

So while there are request flyers from E to S rank, even among E rank quests the number of points differs. Well, no way town cleaning and monster extermination would be ranked the same way.

"Hm, then if, let's say, E rank goes from 0 to 99 points and D rank from 100 to 199, if 100 points are required to gain D rank then completing two 50 point quests would be most efficient and have a decent success rate, whereas doing quests with ten points assigned to them would be safer but also more time consuming."

"However, failing a job makes you lose a lot of points. Depending on the request there might also be a penalty fee."
