DITTO, absolutely essential in fact. for more than one reason in fact you need to list all bets in date order. then in the next 8 columns across like so, (I'm presuming on a spreadsheet) Supertab Win, Supertab Place, NSW Win, NSW place, Unitab Win, Unitab place, then column 7= SP, and 8 =Top Fluctuation.

Set it up so that it adds up automatically (i.e. sum=( x+z) etc so that you can see at a glance where you will be better off BEST TOTE +SP or Top Fluc etc etc
