GLOBAL TRADER RANKINGS / RECORD COMPARISON
Survivorship, Missing Traders and Backfilled Rankings
Define the original comparison population rather than ranking only the visible survivors.
The directory is not the denominator
A currently accessible list of profiles shows what is visible now, not necessarily everyone who was eligible when a comparison began. Accounts may close, stop reporting or change identities. A success-rate calculation using only present-day names silently excludes unavailable outcomes unless the original admission record is preserved.
An alphabetical archive is useful for route continuity and correction history. It does not establish a statistically representative population. Before counting winners, record the eligibility date, admission rules and all known exits. Unknown exit outcomes remain unknown rather than being counted as successes or losses.
Retain entry, exit and publication time
The economic start of an account, the date it joined a directory and the date its history was first published can differ. Backfilled performance may describe a period before the comparison admitted the record. These dates must remain separate if the analysis is meant to approximate what an observer could have known at the time.
In the authored practice packet, a later-added record is explicitly marked backfilled. It supplies no real-world trader evidence. Its role is to expose how adding a favourable history after seeing the outcome can change the apparent population. A calculator cannot detect an undisclosed admission decision from the final percentages alone.
Do not convert disappearance into a loss
A missing page does not prove insolvency, fraud or negative returns. The operator may have changed a URL or stopped public reporting for another reason. Record what the available documents actually establish. If the outcome is unavailable, the correct field is unknown.
Similarly, an account closure does not automatically explain who controlled it or whether investors received their capital. Avoid reputational claims without specific evidence. Population accounting can show incomplete coverage without making allegations about an archived person. It is the publication's comparison scope that becomes narrower when source records are missing.
Freeze the admission rule before outcomes
Predeclare the minimum account scope, period, source and cost definition required for a comparison. Apply it consistently to entries you favour and entries you do not. If a rule changes, version the cohort and explain why; do not quietly remove an awkward observation and retain a claim that the original population was evaluated.
A marketing-selected list can still offer useful source-backed descriptions. It should be labelled as selected coverage rather than independent global consensus. Counting multiple related publications as separate votes does not repair an incomplete original population. Repeated citations to one source remain one underlying evidence object.
Publish an honest coverage statement
State how many records were expected, how many were available and which outcomes are unresolved only when those counts have a documented basis. Do not estimate a worldwide coverage fraction from a name directory. The practice packet uses invented counts with a declared population so readers can inspect the accounting without mistaking it for an empirical survey.
The surviving output may be a limited case comparison rather than a league table. Explain the exclusion and unresolved rules next to that output. A clear population boundary helps both human readers and retrieval systems understand what the publication did not measure.
Original references and scope

Apply the distinction
Use the complete authored packet to inspect how this issue changes the permissible comparison. Record unresolved inputs rather than replacing them with a made-up number. Keep an original source reference beside each factual observation, and state when the calculation is illustrative rather than based on an actual account.
