A tracker spends effort the way this desk spends credits: nothing on a trail that has not been proven. The standard model at 6 credits is the tracking tool — cheap, quick, honest — and it does almost all of the work. Premium, edits, swaps and upscalers are spent only on what the tracking already found.
The order is fixed. Prove the character at standard across a full sitting and keep the best third. Repair the near-misses that fail by one detail — an edit at 21 credits rescues a proven frame far more cheaply than regeneration finds another. Swap only faces that judging has passed. Upscale only keepers, at delivery, last.
Premium at 41 credits has exactly one regular job: the frame that fronts the pack, regenerated slowly from a brief the standard sitting already proved. Used that way, premium is a bargain. Used for exploration, it is the fastest way to spend a pack learning what 6 credits would have taught.
Track first, spend on proof, finish last. The kit stays light and the series stays hers.
