I don't know what happened to my splits. I somehow used some odd comparison method, so it looked like a much more insane pace that it actually was.
Because of those splits issue, I thought that I had insane pace going with almost 1 minute of timesave (which obviously wasn't the case). Therefore I played a bit safe in Level 6 which lost me a bit of time. But moreso was just small mistakes that hurt a bit. Firstly when attempting the new damage boost skip I came there are a bad time, since the cycle was going up so I had to wait to even attempt doing it. Secondly I failed the skip, and thus I had only 1 HP left and was forced to do the intended slow route but also with 1 hit away from dying. I also decided to go for the Death Warp since I was at 1 HP and didn't want to go for the top route to end up dying and lose even more time. It loses around 3s, give or take, but I decided to play it safe and went for it.
Luckily though I kept composure and clutched a new record! I would've liked getting a sub 7:30 run, but it's close enough! My Sum of Best is currently at 7:10, with around 22s of time save. Furthermore I'd imagine combining all of my best times from each level a perfect run could probably end up being a sub 7 min run! But for the time being I'm satisfied with what I've accomplished.
