SuperGrok Heavy. Implied weekly allowance ≈$400.5 API-equivalent.

Method

Calibrate the 17-run cohort's $124.85507688 of provider-recorded API-equivalent usage against a 19-percentage-point CLI meter increase (56.0% at 2026-09-23 18:22:15 UTC to 75.0% at 2026-09-25 09:09:24 UTC) over $76.09728984 of deduplicated receipts. Implied weekly allowance ≈ $400.5. Labelled implied, not reported. Monthly is that implied weekly figure ×4, a projection.

$124.85507688 / 0.311739 = $400.51157179563677 ≈ $400.5. The 0.311739 divisor is the report's 31.1739 percentage points. Implied, not a provider-reported quota.

Projection of the implied weekly allowance: ≈$400.5 × 4 = ≈$1,602. Not a separately metered monthly quota, and not four times the cohort.

Lower confidence: the cohort share is a calibrated estimate from two CLI meter readings and logged receipts, not an exact subscription debit. The weekly pool is shared across Grok products.

Measured cohort

Grok 4.7 XHigh, 17 of 18 runs. 19 percentage points × $124.85507688 / $76.09728984 = 31.1739 percentage points of one weekly allowance. The headline share is ~31.17%. The report's planning estimate is ~31.2%. Decimal precision is not measured accuracy.

Processed and generated tokens from the 17 selected Grok CLI result records. The dollar figure is provider-recorded API-equivalent usage, not cash billed on the subscription.

An unverified Turbofan artifact estimates another $27.850909 at its midpoint. Including it would raise the projection to ~38.13% per cohort and ~152.51 percentage points for four cohorts, about $610.82 API-equivalent. Not an eighteenth measured receipt.

Caveats

1. The ~31.17% share is a calibrated estimate, not an exact subscription debit. Token counts and the $124.85507688 receipt are measured; mapping them onto the weekly quota is inferred.
2. Read-only Grok CLI meter snapshots for the same weekly window showed 56.0% used at 2026-09-23 18:22:15 UTC and 75.0% used at 2026-09-25 09:09:24 UTC. Deduplicated CLI receipts between those snapshots total $76.09728984 API-equivalent usage, approximately 96.1% XHigh. The calibration assumes that interval's 19-percentage-point increase came from the logged use and that quota debit scales comparably across the cohort: 19 × $124.85507688 / $76.09728984 = 31.1739 percentage points.
3. Grok's weekly pool is shared across products, so unlogged Grok.com, Imagine, Voice, or Build activity between the meter readings could have contributed to the 19-point change.
4. The calibration interval is mostly, but not entirely, XHigh. Result receipts can also omit interrupted or abandoned attempts.
5. Dollars are provider-recorded API-equivalent usage, a pricing proxy, not money billed on the subscription. See the xAI Grok usage FAQ at https://docs.x.ai/grok/faq.
6. Turbofan is not an eighteenth measured receipt. The unverified artifact estimates another $27.850909 at its midpoint. Including it would raise the projection to ~38.13% per cohort and ~152.51 percentage points in one-week-allowance units for four cohorts; the four-cohort API-equivalent total would be ~$610.82.
7. Do not publish the decimal precision as measured accuracy. The report's planning estimate for the 17 recorded Grok runs is ~31.2%. The headline calibration stored here is ~31.17% (unrounded 31.1739 percentage points). The implied weekly allowance ≈$400.5 is $124.85507688 / 0.311739, labelled implied, not reported.
8. Four identical cohorts are ~124.70 percentage points of one weekly allowance ($499.42030752 API-equivalent). That adds four weekly debits and expresses the sum in one-week-allowance units. It does not mean Grok permits a 124.70% debit in any single week. Against four equal weekly allowances the fraction remains ~31.17%.
