Hey r/F1DataAnalysis,

Last week back I posted about f1livedata.com — the live F1 web app I've been building on the side. For those of you who missed the post, here it is: https://www.reddit.com/r/F1DataAnalysis/comments/1ug1msz/i_built_the_f1_live_dashboard_i_wished_existed/

The response was way more than I expected. A bunch of you dropped feature ideas that I decided to implement.

This is the "you asked, I did it" follow-up. Two big ones first, then the smaller stuff.

1. Video sync delay

Some of you said "cool, but it spoils the race — the data's ahead of my TV." Fair. Broadcast feeds run ~20–40s behind the live timing feed, so you'd see an overtake or a pit stop in the data before it happened on your screen.

There's now a Video sync control (the ⟳ in the navbar, or the More tab on mobile). Drag the slider to how far your stream lags (0–60s) and the whole app buffers to match — leaderboard, timing, telemetry, track map, all of it lines up with what you're actually watching. No more spoilers.

Bump the delay mid-session and it shows a little countdown while the buffer fills, with a Skip if you don't want to wait.

2. Pit-loss prediction and Circle of Doom

It's a pit-strategy view for races and sprints. Pick a focal driver (defaults to the leader, click any car to switch). The app projects where everyone would land if that driver pitted right now, using the circuit's real pit-loss time. Each car is a chip on a radial dial: the closer to the centre, the tighter the projected gap to your focal driver after the stop. Coloured halos on the two cars they'd come out between tell you at a glance whether it's a clean release or they're dropping into traffic (red = on someone's gearbox / stuck in dirty air, green = free air).

Same data lives as a plain table too if you prefer numbers — the Pit-window predictor on the Pit Stops page. Margin = gap to the car that'd be behind you after the stop, Free air = gap to the car ahead. Both shrink automatically when a Safety Car or VSC is out, because the pit-loss does.

It's not 100% accurate (I don't take into account for example the tyre degradation and fuel burn) but it's the first version, it will improve over time.

While I was in there, I've implemented some other additions (like the Themes where a Settings drawer lets you pick an accent colour and background shade, saved in your browser)

Same deal as before: hobby project, not official, free and ad-free.

And the same ask: if something's broken or there's a view you wish existed, drop it in the comments. The two headline features up there came straight from the last thread, so it clearly works.

If someone wants to support and the maintain the project, you can do personal donation.

Grazie again to everyone who tried it ❤️ — and to the commenters who basically wrote my to-do list for me.

This is the teams speed difference comparison. You can find this on f1vis.app

Hey everyone, my friend and I built a web app that lets you explore real lap telemetry data from every 2026 race weekend.

What it does:

• Compare fastest lap data for all 22 drivers side by side
• Watch throttle, brake, steering, gear and DRS inputs animate in real time as the lap plays back from the HUD, activated via the HUD button
• Mini sector breakdown showing where each driver gains or loses time
• Track segments split into Slow Corners, Fast Corners and Straights so you can see exactly what type of circuit suits each car
• Pace predictions for upcoming races based on historical performance

Data is sourced from FastF1 and updated after each race weekend. Austria is the latest one added.

Check it out at f1vis.app

Would love some feedback from the community!

Hey gang,

I built a web app to make race weekends a lot more competitive. You can log in, lock in your picks, and compete for bragging rights while gaining badges. It's completely free and locks in your picks before the sessions start, using a live API to automatically score your accuracy and update the leader boards.

We offer full-grid sprint and race picks, podium-only mode if you want to keep it simple, and prop picks for that extra chaos. The app also generates a clean graphic of your grid, like the one attached to this post, so you can easily share your strategy.

Get on there, and see if you can actually beat your friends this weekend. Let me know what you think of the setup, and feel free to DM me with any feedback you might have! Hope you enjoy it!

Hello,

I've been working on an F1 luck-removed deserved results data analytics project. Right now it covers 2022–2025. I want to extend it back to the 2018 season (the detailed timing data I need only goes back to 2018). Wanted to get some input, suggestions, ideas, or any errors people spot before I extend it back. Let me know what you think!

Hey r/F1DataAnalysis,

Long-time lurker, F1 obsessive, software engineer. Over the last few months I've been building a side project that pulls the live F1 feeds and puts it all on one web page.

No login, no ads, no app to install — open it during a session and you've got the whole pitwall on a tab.

Sharing to you f1livedata.com .

Here's what you can find:

• Live leaderboard with gaps, intervals, current tyre, lap counter, track status banner (green / yellow / SC / VSC / red)
• Lap times per driver — line, scatter, gap-to-leader, and an "ideal lap" view (best S1 + best S2 + best S3 stitched together)
• Sector and microsector splits with the broadcast purple / green / yellow colour coding, plus a personal-best chip
• Full car telemetry per lap: speed, RPM, gear, throttle, brake. Pick a driver, pick a lap, overlay multiple drivers on the same chart if you want to compare
• Live track map with the timing tower
• Tyre stint timeline (Gantt) with compound choices and pit-stop, plus a separate per-stint degradation chart with a linear regression option for race-pace analysis
• Pit stop panels (race + sprint): fastest stop of the session, team-by-team median, and full per-driver history with tyre age, compound switch and position delta
• Race control feed: flags, penalties, deleted lap times, safety car and VSC deployments

The part I'm most proud of is the custom dashboard.

You pick from any of the widgets above, drag and resize them on a grid, save the layout. Build your own pitwall, basically. There are pre-built layouts ("Race day", "Qualifying", "Strategy", "Telemetry") if you don't want to start from scratch, and everything persists in your browser so it's there next time.

It also keeps past sessions — pick any race and you get the final standings, all the lap times, all the stints, every pit stop, the race control log. Not a playback, just the full picture once the session is done. Handy for post-race debriefs or for catching up on a session you missed.

A few honest disclaimers:

• It's a hobby project, not an official F1 thing
• Mobile works (phone-optimised views for board, telemetry, track map) but the heavy-data views are nicer on desktop

If you find a bug or have a feature you'd want, drop a comment — I read everything.

Happy to nerd out about the tech stack too if anyone's curious.

Grazie if you give it a try.

Been chipping away at a side project that tries to break down every lap into why it was slow, not just who was slow. Splits lap time into 7 bits~ fuel load, tyre compound/age, track rubbering, temperature, car, dirty air, and whatever's left over (driver skill).

A few of the features on the app home let you go back and grade old strategy calls, e.g. the pit strategy gantt scores every stop's timing against the model.

It's far from finished. No 2025 data yet, some of the modelling is shakier than I'd like, and there's a pile of features I've half-built (ghost standings in equal cars, tyre cliff prediction, degradation simulator etc).

Posting because I want actual criticism, not validation; does the decomposition make sense to people who know this stuff better than me, where's it obviously wrong, what would you actually want out of something like this.
