Short answer
Do not confuse a horse’s saddlecloth number, its published barrier draw and the physical stall used after scratchings. A scratching can alter the loading arrangement without making those three numbers interchangeable. Check what “winning barrier” means in the market, then compare the final official barrier information and any stewards’ notice. There is no safe rule that every late scratching renumbers every wager.

What to check
Verify whether the book uses actual stall or original barrier draw and record a card with a late scratching.
