The grading seems vastly different to that in UK.

I have found two sources that seem to cover this racing in some detail. The first is trackinfo which offers cards and results as well as replays. The other simply called greyhounds which offers several pay on the day services but im unsure how good these are?

Are there any other good sites?
Which are the stronger tracks?
The times on the trackinfo racecards seem to be incorrect at times with dogs regularly finding 10 lengths over there previous dozen runs.

Do these cards not take into account track conditions?

Any advice greatly appreciated

GREYHOUND CHANNEL AND BETAMERICA I WOULD
CONSIDER FOR BETTING - THEY DO NOT INCLUDE THE EXACT
SAME TRACKS- DERBY LANE BEING AN EXCEPTION OF NOTE.

GRADING DIFFERENTLT - HECK YES-FEEL MY PAIN COMPETING
IN YOUR TIPPING CONTEST LAST YEAR. MOST RUN AA,A,B,C,D,M
SOME TRACKS USE E CLASS OR J FOR JUVENILLE RACERS.
3 RACES OUT OF TRIFECTA RACER MOVES DOWN A GRADE IE
DOG INISHES 4, 5, 6, IN GRADE A DROPS TO B CLASS.
NO PURSE CONSIDERATIONS.

TRACKINFO IS A GOOD SITE. THE JACKSONVILLE WEBSITE HAS VERY
DETAILED INFO ON THEIR DOGS ON THE HANDICAPPING TAB.

SOUTHLAND -THE VERY BEST
WHEELING - NEXT BEST.
TRI STATE- A TOUGH HANDICAPPING TRACK A NOTCH BELOW WHEELING.
SOME FLORIDA TRACKS ARE AT THE LOWER END ALTHOUGH
DERBY HAS SOME VERY NICE RACERS.

YOU WILL FIND A DOG RUNNING FLAT AND FIRE A BIG WIN.YES.

THE PROGRAM PAGE WILL DENOTE TRACK CONDITIONS.

HOPE THIS HELPS SOME.
