yeah you can get a free trial of this https://statisticsports.com/en/live-games
I've been using it for years to gain an edge as a live soccer bettor. your guy is probably not screwing you he's just seizing on opportunities to hit big totals on a game that is getting a ton of chances and just waiting for them to start going in. as a player you can adjust the settings to spit out betting opportunities when certain conditions are met. that's what your guy is doing... nothing seedy or mischievous, just putting in the time and work required to beat your ass
from a bookies perspective it time stamps the current odds every minute when you click on game history
RT.........is betting soccer one of your best money makers as far as all the sports gambling you do?
