Find where the margin disappears
Begin with the same companion and a familiar course. Notice your screen position after a completed gap, then watch what happens during the next turn. A margin that shrinks during a large loop points to lost forward progress, even if the loop avoids every branch.
The warm edge tint warns when you are close to the left side. Treat that as evidence to inspect the route. It is not a direction arrow telling you which way to flip.
Change the loop that caused the loss
On the next attempt, reverse earlier in the problematic excursion so the heading does not spend as long pointing away from the right. Observe whether this leaves more screen margin by the next crossing.
Do not simply tap rapidly when the warning begins. A flip changes curvature, not speed or instantaneous heading. If the companion is already deep into a backward arc near the edge, the available space may be insufficient for recovery. The useful intervention belongs before that point.
Balance forward movement with safe positioning
A route that stays far from the left edge but collides with every branch is not a solution. Judge both outcomes: did you keep more forward margin, and did the next opening remain reachable with body clearance?
The baseline camera pace grows with score up to a limit, so a wasteful early habit can become more costly later. Continue the drill only long enough to identify that habit. Then return attention to the next opening, keeping the left margin as a secondary check rather than staring at the warning area throughout the run.
