Mike Knoop argues intelligence is capped at optimal decision-making

Mike Knoop argues intelligence can be measured as the ratio of a decision's quality to the optimal decision, capped at 100%.

He says Astra is already 80% optimal on ARC v3 speedruns and identifies horizontal data acquisition and efficiency/cost as the most plausible near-term areas for RSI. Background from @mhmazur reports that GPT-6 Astra scored 100% on the 25 ARC-AGI-3 public games using 6,485 actions versus a human baseline of 17,135.
