Claim
Raw speed without held understanding is not reading skill.
What the eye science says
Decades of eye-movement work show that skilled reading is not a race against the clock. Readers who push pace without protecting meaning trade away the very signal that makes the text useful — the ability to answer for what they just read. Rate and understanding move together; either alone is an incomplete picture of skill. Public claims that treat raw words-per-minute as proof of mastery routinely fail when comprehension is measured with the same seriousness as speed.

What SPEED/READ does
We score effective WPM: raw pace multiplied by quiz accuracy, and only sessions that clear an ≥80% comprehension gate count toward the number we save and show. Training pushes you to go faster while the quiz holds — not to inflate a vanity readout. Adult professionals get a number they can defend in real work, not a gym-wall brag.
What we refuse to claim
We do not promise 3× gains, full comprehension at 1000 WPM, or any headline that treats raw WPM as the product. If the quiz fails, the pace does not count.
