Common questions
Does the market already price in the Ripon draw bias?
With no strong bias to price, stall position at Ripon is rarely a value angle either way — judge each race on pace and ability.
What do IV, A/E and PRB mean?
IV (Impact Value) is the group's win rate versus all runners in the same races — 1.00 is neutral. A/E is actual wins versus what de-overrounded Betfair prices expected — below 1 means the market over-bets that group. PRB is the mean percentage of rivals beaten, a finer-grained placing measure.
Keep going
Method: stall numbers grouped into field thirds (low/middle/high) per race, so field size never skews the groups; IV against same-course same-band baseline; A/E against de-overrounded Betfair SP. Small samples are flagged rather than hidden. Racing Alpha does not accept bets. 18+ · BeGambleAware.org.
