Abstract
In Phys. Rev. Lett. 113, 120404 (2014) [arXiv:1403.2362], Ferrie and Combes claim that weak values could be a statistical artifact caused by correlations between the disturbance and the post-selection condition imposed on the output. In this comment, we show that the disturbance caused by a weak measurement is sufficiently low to definitely rule out the model proposed by Ferrie and Combes.

Comments
Short comment on Ferrie and Combes, arXiv:1403.2362 (Phys. Rev. Lett. 113, 120404 (2014)); quantitatively discusses the requirements for the avoidance of statistical artefacts in weak measurements; v2 is unchanged except for the wrong arXiv references that were added automatically in the first submission
