  The `Red Supergiant Problem' describes the claim that the brightest Red
Supergiant (RSG) progenitors to type II-P supernovae are significantly fainter
than RSGs in the field. This mismatch has been interpreted by several authors
as being a manifestation of the mass threshold for the production of black
holes (BHs), such that stars with initial masses above a cutoff of $M_{\rm
hi}=17$M$_\odot$ and below 25$M_\odot$ will die as RSGs, but with no visible SN
explosion as the BH is formed. However, we have previously cautioned that this
cutoff is more likely to be higher and has large uncertainties ($M_{\rm
hi}=19^{+4}_{-2}M_{\odot}$), meaning that the statistical significance of the
RSG Problem is less than $2\sigma$. Recently, Kochanek (2020) has claimed that
our work is statistically flawed, and with their analysis has argued that the
upper mass cutoff is as low as $M_{\rm hi} = 15.7 \pm 0.8M_\odot$, giving the
RSG Problem a significance of $>10\sigma$. In this letter, we show that
Kochanek's low cutoff is caused by a statistical misinterpretation, and the
associated fit to the progenitor mass spectrum can be ruled out at the 99.6\%
confidence level. Once this problem is remedied, Kochanek's best fit becomes
$M_{\rm hi} =19^{+4}_{-2}M_{\odot}$, in excellent agreement with our work.
Finally, we argue that, in the search for a RSG `vanishing' as it collapses
directly to a BH, any such survey would have to operate for decades before the
absence of any such detection became statistically significant.
