Australian Horse & Greyhound Racing Forum

Hi all, i am trying to find someone who has purchased the "greyhound racing system" from How to win Roulette | Roulette Staking Plan | Free Roulette Strategy , the reason i ask is that i am looking to purchase it but i am still a little skeptical as to whether it actually works. They claim to have a 61% s/r on winners as well they have a 91%s/r on the over all placing of greyhounds. it says on the website that they look at wentworth park greyhounds and the meadows to get this s/r. would it really matter what greyhound tracks you were looking at to find winners with a system? if anyone has tried this system can you please let me know how you went with it, i know it is only $50 but i have wasted enough money over the years on gambling systems that work up until the point where i buy them (funnily enough) and then seem to go downhill right after.
