a) which is why Ego gets in after his performance from wide draw
b) Field of 6 there isn’t as much need to get up close to the speed because the worse you will be is 2 lengths back and ready to pounce. This gives the leader an easier lead. Whereas with danger of being out the back you will see more early speed from out wide eg Balraj and Boncel last week. This early speed brings more horses into the race as the leader doesn’t have it on their own terms. I’m sure with horses like Mach Dan/Bondi Lockdown in a 6horse field with King drawn 1 they would be more inclined to go back but in an 8 horse field there may be some temptation to chance their arm – with the early speed battle tiring out King and bringing horses like Bundoran into the race.
Eg win likelihood with 6 horses might look like:
Leader: 50%
Death: 10%
Behind leader: 15%
1-1: 15%
2 Pegs: 5%
1-2: 5%
But win likelihood with 8horses might look like
Leader: 25%
Death: 10%
Behind leader: 15%
1-1: 15%
2pegs: 15%
1-2: 15%
3pegs: 3%
1-3: 2%
I think HRNSW probably have other reasons but that’s my logic for preferring 8 horses than 6. It evens out the winning chances.
