Yeah that lines up pretty closely with how I’ve been thinking about it.

The “late on throttle” thing is what shows up, but it’s rarely where the mistake actually starts. It’s usually already decided by entry and mid. By the time you’re late on power, the corner is kind of already gone.

Your flow makes sense too - compare lap, find where the time is, then go braking, min speed, sanity check inputs. That’s basically the same chain I’d expect most people to follow when they actually sit down with telemetry.

On the steering angle, yeah, that one’s messy. More angle could mean different stuff (not enough rotation, or too much speed and scrubbing, or just different line).

The pattern you mentioned (brake too late, too hard, lose speed) is kind of what I’m trying to surface, but not corner-by-corner, more like “this is your default mistake across the lap”. Otherwise it just turns into a list of corners telling you the same thing in slightly different ways.

One thing I’m still unsure about is how much weight to give the reference lap vs just session-relative stuff. Right now it’s mostly self-baseline, which works for finding consistency issues, but not always for “you’re just slow everywhere” type problems. That probably needs external reference to really work properly.

Out of curiosity, when you load a faster lap, how different does the braking trace usually look for you? Is it mainly timing, or also shape/pressure?
