We show that the Holmes--Thompson area of every Finsler disk radius $r$ whose interior geodesics are length-minimizing is at least $\frac{6}{\pi} r^2$. Furthermore, we construct examples showing inequality sharp and observe equality case attained by a non-rotationally symmetric metric. This contrasts with Berger's conjecture in Riemannian case, which asserts round hemisphere extremal. To prove ...
