Shaun,

I would definitely include the investment on every race as per freddy's post - this is the only way to get a good idea of your strike rate and overall profitability. I would suggest you record every individual bet as well as the all-up results so that you can guage how effective your all-up betting is. Depending on your strike rate you may find that 2-race, 3-race or even 4-race allups give better results - but the only way to find out is if you have details of all your bets.

Whilst I can see BigO's point that you have only put up $10 of your own money you are really risking the full amount - you always have the option of placing the bets individually so the argument that it is a single bet is not really valid.

Just my opinion :smile:
