Agreed on the framing, and the push is fair.
25.7 (single-stream) and 601 (aggregate under concurrency) aren't the same axis β you're right. The 23.4Γ is a system-level number, and part of it is batching that any MoE gets for free. That isn't the VKAE claim, and we'll present it as what it is rather than fold it into the speedup.
What the paper leads with is the controlled comparison: identical concurrency, batch, and harness, VKAE on vs. off. Single-stream and the throughput ceiling stay as separate, labeled context.
Same discipline on quality β the tail, not the mean: long-context recall and the hard subset, measured against VKAE-off on identical inputs. If it doesn't hold there, it doesn't ship.
To your question directly: VKAE-on vs. VKAE-off at identical concurrency. That's the headline.
