Live sports events results are based on a contest between 2 teams, several humans or several animals.
The larger the animal the more relevance can be related to previous performance & therefore “form” systems may give the astute gambler an assumed advantage.
Smaller animals i.e. Greyhounds are susceptible to feeding irregularities & bumping at corners so are intrinsically more random.
Machine gambling is labelled as Random.
Return to player is calculated over a minimum of 136,000,000 events.
A player achieving a “win” will statistically have to wait a long time to get the same result again.
And lose a considerable amour of money doing so.
This “randomness” was clinically tested by BBC Panorama.
