Two different statements deserve two different scoring frames
Running separate leagues is important because the strategies being evaluated are genuinely different.
The benchmark-aware participant is saying, in effect: "Judge me as an active PM or directional trader relative to a declared market opportunity set."
The market-neutral / alpha participant is saying: "Judge me on residual skill after stripping out obvious market and sector drift."
Those should not share a leaderboard because the scoring logic should not force one style into the frame of the other.
