02 · Decision matrix
One decision, three separate questions
Capability ignores price. Relative Value adds the current dataset offers and your priorities. Keeping them separate prevents a cheap product from being mistaken for the faster product.

Both products are normalized within the same in-stock market frame per preset. A check marks the higher Relative Value; a difference of 3 points or less is shown as practically even.
Crossover price is loading. The switch-over point and Strong Value threshold appear as soon as today's offer snapshots are confirmed in your browser.
03 · Price crossover
The price changes the answer
Current offers, crossover points and Strong Value thresholds answer different questions. Thresholds are calculations, not price forecasts.
