The calibration anchor

01

Two runs, held side by side, so drift in the ruler is visible.

The workbook preserves both the original benchmark anchor and the current observed run: hit 87.6% against 87.406%, lock 12.4% against 12.018%, hit-week quartiles of 14/17/21 against 15/17/20. Keeping both on the same sheet is deliberate. A benchmark that silently re-anchors itself each time the model changes cannot detect that the model changed, and the operator loses the ability to say whether this month's comparison used the same ruler as last quarter's.

The hit-week trap

02

Median hit week is a property of the survivors.

Hit-week percentiles are calculated only among paths that reached the target. Failed paths and locked paths are excluded from that statistic entirely. A fast median hit week therefore says nothing about safety on its own, and it is never a deadline. Read hit speed beside completion probability and lock probability or the number will flatter the system by construction, because it is the average finishing time of the runners who finished.

Anti-misuse

03

The rules exist because each one has a failure mode attached.

The standard writes its prohibitions out rather than leaving them to judgement, because every one of them describes a way an operator has talked themselves into risk using a benchmark as the excuse.

  • Do not use the benchmark to justify revenge trading or catch-up trading.
  • Do not compare a partial week to a full-month band without labelling it provisional.
  • Do not judge the system by equity alone: equity, drawdown, gate dwell, tier usage, exposure, and throttle efficiency are read together.
  • Do not override the throttle because the live account is below benchmark. Underperformance is a reason to diagnose, not to force risk.
  • Do not modify benchmark assumptions without versioning the workbook and updating the standard.

The strong rule

04

Below benchmark and worse drawdown is never an argument for more risk.

The standard states this as its one unhedged rule, and it is the position most likely to be argued with in the moment. When live performance sits under the bands and drawdown sits outside them, the two readings together describe a system that is both underperforming and over-risked. The answer is diagnosis, containment, and a model-to-live mismatch review. Adding exposure to a system in that state converts a recoverable quarter into a locked account.

How MARS uses this

A ruler needs marked gradations, and this table is the marking. Each percentile row carries a defined operator read — the doctrine that live performance is compared against bands, not wished against targets, starts by giving every band a name and a permitted meaning.

How it benefits you

Percentiles become vocabulary instead of decoration. When you say 'we are tracking P60', everyone - including future you - knows exactly what that means, and sizing debates end by pointing at the P10 row rather than negotiating with optimism.

The ruler, printed: each band with its horizon values and the one interpretation it is allowed to carry.
