Here is the calculation behind it : The time to start and exit a game is 833 ms , multiplied by 98 to get the time to prepare for who you are achievement, after research 633ms is the time to jump and stomp as fast as possible assuming player is lucky to always get booster below them , they'll get : 27s328ms Because after multiplying 633ms by 12 the number of platform the player needs to get without booster and adding to it 4s933ms the time of the booster effect × 4 , we get 27s328ms to get score = 100 we add 833ms to start and exit the game for doesn't matter achievement, adding 10s900ms waiting for highscore animation, and unlock animation for level one and doesn't matter we multiply 633ms by 50 to get 50 platforms without booster perfect time , then we'll add the 5 booster time + the time for the booster effect to reach 200 score , we'll then add 633ms × 20 the number of platforms without booster , after that we add 433ms the time it took to start the game , and finally the 1s to end the achievement animation, to get a final time of : 3min16s036ms
