OK, so today I started doing serious runs today and am very impressed with the times I've been getting. For reference the world record is 19:06, my personal best is 20:13. That's a wide gap, but X6 has a lot of RNG and my former record was mostly unchallenged, so I didn't optimize it to full effect at the time.
There are a few places with obvious improvements, Shield Sheldon, and Metal Shark Player being the two I need more focus on.
My times today were very solid for being back in the game for only a few days. It took me years of work to get to a sub-21 time in the first place, and I managed to get four 20:XX times today and they all sucked!!!!
Lots of work to do to cut off that minute gap, but it's possible. I just need luck and patience. I've never felt this consistently good at my game, and it feels good. I want to achieve an 18:XX time by the end of August, so we'll see
