Issue No. 187 · Friday, March 14 — Data
Cluttered analytics war-room with flat dashboards on multiple monitors

Issue No. 187·Data

The dashboard your CEO loves is hiding a 38% miss in the metric she actually measures.

A teardown of the most-cited "activation rate" chart in B2B SaaS, why its denominator quietly doubled in 2023, and what your growth team should be reporting instead. A 14-minute read with the underlying CSV.

Recent dispatches

Long-form arguments for analysts who'd rather be right than optimistic.

Four pieces from the past month — growth teardowns, dashboard dissections, post-mortems, and methodology critiques. Average post length: 2,400 words; each one fact-checked against an original dataset.

  1. Growth teardown

    Why your "weekly active users" number has been wrong since the cookie deprecation — and the query that fixes it.

    By Devi Okafor · 11 min read · March 7, 2025

    A post-mortem on three SaaS companies whose WAU charts quietly diverged by 30–60% once third-party identifiers disappeared. Includes the dbt model we used to reconstruct the cohort.

  2. Dashboard dissection

    The "engagement" chart that posted Notion to a 40% retention miss — annotated line by line.

    By Miguel Saldaña · 9 min read · February 28, 2025

    An examination of how a stacked-bar visualization conflated two distinct user states, why the underlying SQL grouped by an inconsistent time grain, and what we'd ship instead.

  3. Post-mortem

    A retail chain's "best quarter in five years" turned out to be a revenue-recognition error. We traced the line item back.

    By Priya Raman · 17 min read · February 21, 2025

    The single footnote in the 10-Q versus what the dashboards were reporting internally — and the meeting agenda that would have surfaced the discrepancy two quarters earlier.

  4. Methodology critique

    "AI-powered analytics" is mostly a regression with extra steps. A reproducible benchmark across 14 vendors.

    By Tomás Lindgren · 13 min read · February 14, 2025

    We ran the same 40 natural-language question benchmark across 14 "AI analytics" products. Average accuracy against ground truth SQL: 41%. We publish the prompts, the answers, and the grader.

The Dashboard Roast

A standing audit of dashboards other analysts won't touch.

Every quarter we publish anonymized, line-by-line critiques of dashboards submitted by readers — 4,200+ audited since launch. We grade on metric definition, denominator consistency, time-grain, and the question the chart claims to answer.

  • Metric definition. Does the numerator match the denominator across every filter on the page?
  • Time-grain honesty. Are daily, weekly, and monthly series computed on the same calendar boundaries?
  • The leading question. Strip the chart — does the title still tell a single, falsifiable story?
  • Vanity checks. Is any series present that the team would not, in writing, defend in a board meeting?

From the editors

"We started this publication because every analytics post we'd read that quarter was either a vendor brochure, a recycled Medium post, or a takedown by someone who'd never shipped a dashboard. We wanted the thing we wanted to read: long, evidence-first, written by people who've sat in the operator seat when a chart broke at 2 a.m. Anti-hype isn't a posture — it's an editorial standard."
