If you have ever finished in the top 50% in a game then you are not supposed to compete at Adventurer class.
The objective of Adventurer class is to allow novice players a chance to get into the GOTM competitions "at the shallow end" with a few aids - "life preservers", or "inflated arm-bands". It is not intended as a refuge for more experienced players who want an easier ride for a month. This *is* a competition, after all, and its primary objective is to help players to develop their skills under a variety of game conditions. Once you have learnt to play without such aids, you should really avoid using them again.
