Your totally wrong on this one I'm afraid its not a complex equation. It doesn't matter whether he has multiple runners in a race.
Many trainers have more than one runner in a race there is nothing to be factored in to a strike rate equation as a consequence of this.. as you give yourself equally a better chance of winning the race as you do not winning it. If you have 1 runner in each of 30 races or 2 runners in 15 of these races the maths is the same...winners over runners.
However the real issue is the falling strike rate of AOB and the reasons behind this ?
Are you for real? How can you honestly argue that having more than 1 winner in a race doesn't have an impact on your strike rate? Sorry to pinch Quel's comments but I am also gobsmacked. I suspect AoB could win every classic in the world in one season, train 23 Cheltenham Festival winners, the Grand national winner, win the Eurovision song contest and find a cure for cancer and you would still find something to criticise him for.
If AOB could have more than one winner in a race he really would be something special![]()

If someone can show me a statistical model that proves I'm wrong I'd be delighted.
