The figures behind the verdict, as the engine served them.

An averaging oracle makes an attacker outweigh genuine trading as well as move the book. A market with no genuine volume has no such defence.

Cost of a 50% move, order book only: 0.36 USDC (shortened; full value 0.368115 USDC)
The target is reachable through the order book
Genuine volume in the oracle window: 0 USDC
Over the last 900 seconds (15 minutes), after the genuine-trade filter
Cost against genuine volume: not computed
Below 1, moving the price is cheaper than all genuine trading across the window. Not computed when there was no genuine volume or the target is unreachable
Total attack cost: 0.36 USDC (shortened; full value 0.368115 USDC)
The move, plus the genuine volume an averaging oracle forces an attacker to outweigh
