Portsmouth vs Charlton Athletic Betting Tips

Our predictions are powered by Betformatics, our specialist technology partner in sports data management and mathematical modeling. The model analyzes extensive match data including recent form, head-to-head records, expected goals (xG), home/away performance differentials, and real-time odds movements across major licensed bookmakers. We calculate our own probability for each outcome and compare it against bookmaker odds to identify potential value.

Value indicates whether our model sees an edge compared to bookmaker odds. A value of 120% means we calculate 20% higher probability than the odds imply.

Example: If odds of 2.00 imply 50% probability but our model calculates 60%, the value is 120% (60÷50). Above 100% suggests potentially favorable odds; below 100% suggests unfavorable. This is a mathematical indicator, not a guarantee.

The stake figure reflects our model's confidence weighted by perceived value—higher numbers indicate stronger confidence. These are relative indicators for comparison purposes, not recommended bet amounts. Always determine your own stakes based on personal bankroll management.
