Implications on solutions to i) value effect and ii) low volatility anomaly

Figure 5 presents returns (ROI) from betting on tennis games at various odds in various games; e.g., the average returns from having 3738 bets on players at odds of less than 2.25 was -3.36%. What implications does this have for proposed solutions to i) the value effect and ii) the low volatility anomaly?
