The likely range from this test runs from 54.7% to 77.7%. A wider range means more uncertainty.

  • This uses the recorded source-linked result, not a fully checked market-price return.
  • This is a look back at data Tradour had already seen, not a fresh test on new examples.
  • Some examples share the same company or market event, so they may not be fully independent.
