Clover is given hundreds of runs with who knows how many attempts in each one of those runs, which is far more than enough for an average UT player to complete Undertale hundreds of times over. For an example, let's say that an average player has 50 attempts to complete Undertale per run. Now, let's multiply that amount of attempts by 150, which could be how many runs Clover roughly has. And they'll get 7500 attempts to get past every enemy or obstacle and reach Asgore on the main path, that's how absurd it is.
