OK, here is my scoring rule of thumb in what classification a player should be considered in regards to Donkey Kong.
0 to 100,000 is Beginner level. This is a person who has still not passed the 3rd elevator.
100 to 300,000 is Recreational level. The person who has been playing from time to time the past few years, but never really seriously is recreational.
300 to 500,000 is what I would call the Intermediate level. This is the person who takes the game on a somewhat serious level
500 to 700,000 is what I would call expert level. This is the level where the springs are no longer that much of an issue, and the person has learned the more complex barrel jumps.
700,000 to 900,000 is what I would call master level. If you can get to around the end of the game you have mastered it.
900,000 to 1,050,000 is what I would call the grand master level. This is the point that not only are you killscreening, but you are incorporating harder to get point pressing techniques . This is where the herd really starts to thin out.
1,050,000 to 1,200,000 is what I would call the Elite level. This is where you are one of the best in the game. You are now the creme of the crop in regards to Donkey Kong play. This is the level where you get excluded from some competitions because you are too good.
1,200,000 plus is All Time Elite. A person who gets this score is not only elite for this time period, but will be among the elite of all time whenever the game runs it's course whether it be 50 years from now or 1,000 years from now.
