You're in the wrong at 0:50, I would have personnally thought that was intentional if I was in the Subaru. You brake way too early but that's not the most dramatic part there (although the guy probably took an undeserved SR penalty), but the line change after that. Once you start your braking, you're expected to hold your line until turn-in point (doing this will also allow a driver who misses his braking point behind you to avoid you more easily).
1:20 Spoon Curve > not dramatic, since you're holding the inside, personnally I would have expected you to brake early and switched to the outside and try to cross-overtake.
1:35 130R > I'm not so sure, he turns in too early with a car aside, but looking at how you approach that corner and the fact you don't brake that much, I think you might have gone off-track if he wasn't there, thus taking him out as well even if he didn't hit you first. Not entirely sure there, but I don't see how you could have let enough space at the exit anyway.
3:40 130R > You slowed down earlier this time, but just by lifting off, which led him to misjudge the space available. I wouldn't put anyone at fault there, although this might have been prevent on his part by using the radar. Positions didn't change because of that so that's not something I'd make a fuss about.
Out of curiosity, what DR are you ? I think you mostly lack experience in close battles.
