How settd works

Canonical Run

We pick the best run from each session to represent your 'setup of the day'. Priority: your pinned run first, then the highest-rated run, then the last run. This canonical run is what feeds into trends, insights, and the Setups list.

Change Tracking

When you make a change between runs and rate the result, we track whether that change helped or hurt. If Run 2 has a higher rating than Run 1 after you changed fork PSI, that's a positive signal. Over many sessions, patterns emerge — some changes consistently improve performance.

Stuck Changes

If you make a change and keep it for 3 or more consecutive sessions without reverting, we flag it as 'validated'. These are your proven improvements — changes you've tested and committed to.

Setup DNA

We look at where your top-rated sessions (4+ stars) fall within your personal range for each setup field. If your best sessions consistently use fork PSI in the bottom third of your range, you tend to run softer. No comparison to other riders — just your own data telling you what works for you.

Anomaly Detection

We flag sessions where a setup parameter is more than 2 standard deviations from your average at that venue AND the rating was low. These are setups that were unusual AND didn't perform well — worth investigating.

Your Data

Your setup data is yours. We never share, sell, or aggregate it. Other users cannot see your geometry, suspension settings, or any other data unless you explicitly share it via a portal link. This is especially important for teams running prototype frames or proprietary suspension tunes.

Geometry Engine

When you adjust headset cups, fork offset, wheel size, or other geometry-affecting parts, our engine cascades the changes through trigonometric calculations: head tube angle affects trail, which affects stability. Seat tube angle shifts with frame tilt. BB height changes with wheel size. Every value shows a 'why' breakdown explaining which adjustments contributed.

Trends

Sparklines on the bike page show your 4 key values (fork PSI, shock, front/rear tyre pressure) across sessions. Change pills highlight the biggest movers. The full trends page shows detailed change cards with old → new values and percentages.
