RS3 Hiscores Comparison

Compare two RuneScape 3 players' hiscores and highlight skills where players are far apart in terms of relative XP progress, accounting for the exponential XP curve. Features: - Compare any two RS3 players' hiscores - Calculate relative XP progress toward next level for each skill - Highlight skills where progress difference exceeds a configurable threshold (default 10%) - Accounts for exponential XP curve (e.g., 100K XP difference matters more at level 30 than level 90)
