United Kart BWI 2024AUG17 BMW CCA League Event 5 Replacement? 6? Gr.B Heat

Really confused by Kart 26's lines. Either really advanced or really annoying.
00:00 Start of Video
00:03 Start of Race and dropped to 3rd Place because I'm on the outside.
00:07 There was a guy coming up on my right who I was trying to make room for on my right side.
00:20 There's no way kart 34 was going to keep up from the outside if he didn't already cut inside by the time I got next to him. Back to 2nd Place.
00:23 I'm pretty sure he didn't get next to me on the outside so I tracked out.
00:35 Ok, time to chase down 1st Place.
1:01 57.521 in 2nd Place
1:31 Kart 26 is starting to be in my way but is still generally faster.
1:54 52.047 in 2nd Place and lifting off the throttle a lot, now.
2:07 Little bump mid corner. Don't know why there was a speed difference.
2:26 Always faster in Turn 6 from momentum or weight traction.
2:46 52.299 in 2nd Place and really having to let off the gas a lot.
2:51 Still carrying a little speed and I try to see how far it can get me.
2:57 He has to know I'm there but the space is very tight.
3:07 Also a very tight cross in front of me, but he makes it.
3:23 I'm actually not accelerating uphill as fast as he is unless I can carry a fast exit speed.
3:38 52.110 in 2nd Place. 3rd and 4th are catching up.
3:41 I need to pass soon. Maybe he goes wide to block and make it difficult for the next turn.
3:50 I'm past, I see him, I have half a kart length, I'm touching his kart, he should see and feel me there and give me more room. There isn't enough room. The wall goes flying. Other people said there was water that came out of the barriers and got onto the track.
4:01 He goes super wide.
4:05 He still makes it just in front of me to get a good line on the next turn. I have to lift.
4:26 Lifting again to not crash into him.
4:31 53.407 still in 2nd Place
4:34 I decide to make a decisive clean pass.
4:45 I figure he'll back off for the right hand turn since we had contact there last lap even though I still give him space but he is nowhere to be seen.
5:23 51.326 1st Place even with the pass, lap time is already faster. Kart 24 also passes Kart 26 around this time. They were definitely catching up.
5:34 Finally take Turn 4 decently.
6:14 50.861 They are not catching me. Even the engine sounds different.
7:05 51.485 I messed up Turn 4 that lap.
7:41 Nicked the barrier.
7:56 51.184 A little surprised at the White Flag. Uh... not sure why I'm still slow. Turn 4 could have been tighter. I lifted in Turn 7 and might have got back on throttle late.
8:47 50.567 A calmer but still fast lap so probably had better grip.
