Logger data and results
—
Every uploaded session, by track, then event, then driver. Tick sessions to compare their laps, or use "Compare everyone here" on an event. Race sessions show their Speedhive result; the driver is the one the lap times match.
Laps being compared
Race the laps
Every lap starts from the line together. Press play or drag the slider to see who is ahead, and by how much.
Speed round the lap
Time against the reference lap
Above the line a lap is behind the reference at that point.
Engine speed
Slowest speed through each corner, top speed and peak g-forces. Best in each column in green.
Each lap of these sessions: the official Speedhive time next to the logger's own.
Each driver's best time through every section, from all their uploads on this track and direction. Select a time to compare that lap.
Upload logger files
- In the Alfano ADA app, export each session. It makes a
.zipfile. GPS tracks (.gpx) from a phone or watch work too. - Choose your files. Several at once is fine, from different drivers and days, and files already uploaded are skipped.
- Press Upload. Each race session is matched to its heat and driver from the lap times, so you don't need to say whose it is. Only practice (no timed heat) needs the driver's name.
Race heats are matched to the right driver and heat from the lap times. Enter a name only for practice sessions.
Good to know
- Uploads are public on this page under the driver's name.
- Race sessions are attributed by lap times: each lap from the logger is lined up against every driver's laps in every heat that day, and a real match agrees to within a few hundredths lap after lap. So a session always goes to the driver whose laps it is, whatever name is typed in, and nobody can post laps as someone else.
- If two drivers ran nose to tail with the same lap times, you're asked which one it was.
- Sessions that match no timed heat (practice, or tracks without results here) are listed as practice under the name entered.
- Only the GPS trace on the track is kept, not the file.
- Alfano files give speed, position, the logger's own g-forces and engine speed (if wired). GPX files give speed and position; g-forces are then estimated.
- A quick automatic check in your browser keeps bots out.
- Each upload gets a private delete key, kept in this browser. "Copy key link" below copies it as a link, so you can delete the session later from another device.
Uploaded from this browser
Delete session removes it from the site straight away (press twice to confirm). Copy key link deletes nothing: it copies a private link that, opened on another phone or computer, lets you delete the session from there too. Keep it to yourself.
