Delta to best · zero-centred bar
Hero card, below the current-lap clock
Shows how far ahead or behind your current lap is vs the reference lap at this exact distance. Reference = your session-best so far, with an all-time car+event PB as the fallback for the first lap of a session.
How to read it
- Center line = on par with the reference. Fill goes left (green) when you're ahead, right (amber) when behind.
- Fill width saturates at ±1 s — beyond that the number tells the truth but the bar is pegged.
- Numeric readout on the right of the bar shows the exact delta to two decimals, colored the same way (green ahead / amber behind).
- Hero card tint — subtle background green when ahead, amber when behind. Reads without needing to focus.
- Empty state (first lap, no reference yet) → bar empty, text "—".

Per-sector cells · F1 broadcast colors
Three cells below the hero card
Three equal-distance sectors, each lit by its own state as you cross the boundary. Color convention is the one F1 TV graphics use: purple > green > yellow > red.
How to read it
| PURPLE | Personal best in that sector this session. |
| GREEN | Faster than the reference lap's same sector (but not PB). |
| YELLOW | Within ±50 ms of the reference — essentially even. |
| RED | Slower than the reference plus the ±50 ms band. |
| PENDING | Sector not yet completed in the current lap. |
See also Sectors are equal-distance splits — same construction as sector times on /compare. Each cell shows Δ in seconds with the same B − A convention as elsewhere; the color is the additional cue.
Predicted · Last · Best + Theoretical
Three-column card below the sector cells
Four lap times in one card: the running prediction of what this lap will finish at, the last completed lap, the session best, and the sum of your best individual sector times.
How to read it
- Predicted — reference total + the current rolling delta. Updates every frame; reflects what this lap looks like it'll finish at if the current pace holds.
- Last — clock of the most recently completed lap.
- Best — fastest completed lap in this session.
- Theoretical (footer row) — sum of your best individual sector times across all completed laps. The lap time you'd run if you put together your best S1, S2, and S3 in one lap.
Reading the shape
| Theoretical near Best | You're already consistent — best lap is close to perfect for this session. |
| Theoretical << Best | Lots of time on the table — your individual sectors don't line up in one lap. |
| Predicted < Best mid-lap | You're on a personal-best run at this distance. Stay clean. |
Compact track map
Bottom of the page
A slimmer version of the replay track map — same component in compact mode. Shows the session-best lap's route as the reference and a live cursor for your current position.
How to read it
- Route = session- best lap's path. No color-mode chips (the page is driver-glance, not analysis).
- Cursor dot = your live world position. Off-screen / hidden when the game is on a loading screen or pause edge.
- No elevation strip — suppressed in compact mode.
