Class Advantage Projection
What the class read says
The stable looks to have run this horse in stronger races to keep its official rating low — today's class drop may be intentional. Worth watching at a price. Crucially, it keeps finishing ahead of what its handicap mark implies — it looks ahead of the handicapper.
Held its own mid-division in 3 of 3 stronger races — solid form context.
Dropping 2 class levels from its toughest race — well-positioned today.
Class-adjusted form 5.6 /10 (raw 4.0)
