If betting traffic spikes right before a match, figuring out whether it's insider-driven activity means focusing on behavior patterns, not just raw numbers. Tracking timing clusters, repeat accounts, and unusual bet sizing helps reveal whether activity is coordinated or organic. Looking at bet logs and real-time spikes around lineup news or injuries gives similar signals to behavioral heatmaps, showing where activity concentrates or shifts. Sudden bursts from new accounts, synchronized wagers, or off-market odds movement can hint at information leaks, while scattered random betting usually suggests normal hype or fan reactions.
