On a good day, with some better RNG, I can shape off 5-6 min. So sub 2:45 or even 2:40 can be possible!

9/15 // 4/12 // 4/6 Battery Booster (Genesis // X // Ultra)

3/15 // 3/12 // 0/6 Health Booster (Genesis // X // Ultra)

3/15 // 5/12 // 2/6 Stamina Booster (Genesis // X // Ultra)

makes a total of 17/33 Battery Boosters, 6/33 Health Boosters and 10/33 Stamina Boosters ;)
