Separate fact from narrative
Opponent quality, notice period, recent activity and the bout format can help frame a question. An isolated highlight or winning streak is not a calibrated forecast.
Use probability carefully
The inverse price is a comparison tool, not your own estimate. If you cannot explain why your estimate differs and how uncertain it is, a large potential return adds little information.
Watch the market definition
A fighter-to-win bet is different from a knockout or decision selection on that fighter. Check the draw and no-contest terms as well as the price.
