Consistency comes before leaderboard chasing
The public Roblox description says players can race others and climb leaderboards. Until the experience shows the scoring or timing rule, practice one stable route and use the in-game leaderboard as the current reference.
A leaderboard attempt should be different from route discovery. First learn the bike line, the jump decision, and the section that causes a reset. Then repeat the same approach under similar conditions and track one mistake at a time.
