// DON'T YOU DARE MERGE THIS WITH A GLOBAL I WANT TO TEST FAST
// The below query creates 2 derived tables
// The first is just a straight ranking of the leaderboard based on a provided ranking parameter.
// The second is a query that finds the ranking of the requested score
// The third and final query takes the score gotten above and gets the rankings as follows:.
// If the requested score is in the top 5, it will return the top 11 scores.
// If the requested score is in the bottom 5, it will return the bottom 11 scores.
// In all other cases, the second query will return the 5 scores above and below the requested score.
