The latest compilation gives the width of the $1/2^{+},T=3/2$ level of ${}^{11}\mathrm{B}$ as 210(20) keV. This is based in part on the value 230(65) keV obtained from fitting ${}^{10}\mathrm{Be}$($p,{\gamma }_0$)${}^{11}\mathrm{B}$ data. It has recently been claimed that these data can be adequately fitted with a width of 640 keV. We discuss this claim and refit the data. With noninterfering levels, a width of order 400 keV is found. A poorer fit in which a second $1/2^{+}$ level is included gives a width of order 600 keV.
