A bit of luck and frustration with how the CPUs act. Stage 3 was basically a gift that they positioned themselves like that. Suicide moves are also pretty helpful, but can go wrong too like in stage 6. Still has improvements to be made though, that's for sure. Last hit is on 2:48::62 even though the timer was stopped at 2:49::45 and because of starting the run 0:00::12 early.
