What telemetry should a beginner look at first?
Start with lap time, the map, speed, and delta. That is enough to answer the first useful question: where was one lap faster? You can open G-sum and the other channels after you know which corner you are trying to understand.

The main idea
The most useful beginner metric is the one that produces a clear, safe action. Line and speed usually explain more than an advanced derived score when the driving is still changing substantially lap to lap.
What to look at
- Lap times grouped closely enough to compare
- GPS line and track usage
- Speed at entry, minimum, and exit
- Delta gains that remain through the next section
Try this
- Pick one corner, not the entire lap
- Compare a normal clean lap with a slightly faster clean lap
- Locate the change on delta, then inspect line and speed
- Confirm the faster technique did not lose the gain immediately afterward
Keep in mind
Do not treat higher minimum speed, peak G, or a late braking point as a target by itself. Each can make the following phase worse or hide an unstable technique.
FAQ
Do I need brake and throttle channels?
No. GPS line, speed, time delta, and acceleration already support useful comparisons. Direct pedal channels add certainty when the logger records them.
When should I use Combined G?
After you know which corner and phase you are investigating. It is context for grip usage, not a standalone driving target.
