well ive had days in my street fighter days where i did stuff that i felt was impossible for a normal human to do, so i believe anything is possible. i played my most recent good game with 1 death and that was mainly due to running out of time because i was so tired my timing was off on springboard. if i can have 1 death only and it was a silly death, then i think i can do 0 deaths. as for those 3 lives being 90k extra points, if i ever wanna beat marks score since im not as good as him i think i need to have all 3 of them to beat it hehehe
one thing though is i have 2 save states when i have spare time to practice, one loads me right next to the double spark on hideout, so i can practice glitch 1200 timing, other is springboard, i just practice those things, i should try to add quad spark kill combo to my regimen since the top dkjr players can do that while i rely on it happening by luck
