97.6% of words right, from thumbs that miss.
The same taps through the nearest key and Apple’s spell checker get 85.2%.
Simulated thumbs with a steady lean (m toward n, b into the space bar, o toward i, every tap a little low) type the 500 phrases of MacKenzie and Soukoreff’s set twice, 5,428 words, and never fix a mistake. Measured by scripts/eval; every run is in PROGRESS.md.
It moves with your grip.
