I will go even further than Mardi above Thommo & say the only reason why I care where it finishes, the further back in the last 3 starts the more its likely to pay, as spoons like you cannot assess form & are busy looking for blocked runs, 3 wide with no cover, blinkers on, 3yr olds after Xmas & any other shit that can't help you win.
I am prepared to handle long runs of outs & huge draw downs, you don't even have a grasp on the topic.
Whilst you are busy looking for 3yr olds full of Xmas pud with blinkers on first time, using some dream't up margin diff based on a calculation method you got off Wikipedia, I like Mardi & Curious understand that time is far better spend looking for the best possible price.
Back you go to the Princess, her warranty runs out soon.
