What do these axes mean?

Each base is scored 1-5 on seven axes. The composite is weighted: fidelity, value and reliability count for more than the rest. A 0 means insufficient evidence and collapses that spoke toward the centre.

FFB Fidelity ×1.5: How clean and detailed the force feedback signal feels at the rim. Smoothness, slip texture, kerb definition.
Build Quality ×1.0: Chassis, motor, mounts and quick release. How solid the hardware feels under load.
Software ×1.0: Tuning app depth, per-game presets, firmware updates and live telemetry.
Ecosystem ×1.0: Range of compatible rims, pedals and shifters from the same brand and the upgrade ladder above the base.
Value ×1.3: What you get for the money compared to direct rivals at the same torque tier.
Reliability ×1.2: Long-term ownership signal, QC reputation, RMA experience, thermal behaviour over long stints.
Compatibility ×1.0: Platform support: PC, PlayStation, Xbox. PC-only bases are marked down here regardless of how good they are.
