Your dead right there Barny about the Do Your Own Reserch.

How many times have we experienced say a system that does well for 3 months, then breaks even for the next 3 months.

If one does not check these things , we will not know if its what we were expecting.
It may have too many bets for our liking.
It may have too fewer bets to our liking.
Long runs of outs may not be to our liking.

To those Punters who blindly bet any system that is written without back checking ..
STOP doing that.
Do some back checking.
Do some dry runs for at least 150 bets & go from there.
Just because it worked say 10 years ago , does not mean it would still work today.

Work out the longest run of outs you expect, then add 100 to it , so as to work out size of betting bank to be used.
If betting level stakes.

Punting is not an exact science so try & be prepared for the worst at all times.
