The first value in Theorem 1.0.5 of Calegari--Morrison--Snyder (arXiv:1004.0665) is (√7 + √3)/2 ≈ 2.18890, not (7 + √3)/2 ≈ 4.366. The latter is well above the upper bound 76/33 ≈ 2.303 of the hypothesis, so under the typo the disjunct is unreachable and the theorem is strictly weaker than CMS.

The first value in Theorem 1.0.5 of Calegari--Morrison--Snyder
(arXiv:1004.0665) is `(√7 + √3)/2 ≈ 2.18890`, not `(7 + √3)/2 ≈ 4.366`.
The latter is well above the upper bound `76/33 ≈ 2.303` of the
hypothesis, so under the typo the disjunct is unreachable and the
theorem is strictly weaker than CMS.
