I have been looking at CJ Racing, a horse racing tipster from Proofed Tipsters. Tips are available from the website from noon onwards, but there aren’t tips every day. I generally checked between 12:30 and 13:00. Bets are win only.
The blurb states that the aim is a 40%-45% strike rate and 150-point profit a year. With 117 wins from 309 bets the strike rate is 38.7% (average odds of 2.85), so slightly short of target and an overall loss of 5 points is very short of the target. BSP faired better with a final profit of 16.26 points (average odds of 3.2), still below target.
This service does work on Betfair. I didn’t take any notice of odds available at noon, so there is a chance that better odds were available than SP. However, on this data, I will give this service a neutral rating.
