I keep an Excel spreadsheet on DropBox.
Started punting again last October after a four year break.
Have spent £3535 on 21 punts plus £452 on expenses, ie hotel, petrol, train, taxi ect.
Grand total of £3987 for the year.
Certainly not a cheap hobby but its my only vice, don't smoke, drink or gamble, a guy has to some pleasure in life. Great times all in all and looking forward to another good year.
