  We re-examine the XUV luminosity evolution of TRAPPIST-1 utilizing new
observational constraints (XUV and bolometric luminosity) from multi-epoch
X-ray/UV photometry. Following the formalism presented in Fleming et al.
(2020), we infer that TRAPPIST-1 maintained a saturated XUV luminosity,
relative to the bolometric luminosity, of $\log_{10}$(L$_{\rm XUV}$/L$_{\rm
bol}$) $= -3.03_{-0.23}^{+0.25}$ at early times for a period of $t_{sat} =
3.14_{-1.46}^{+2.22}$ Gyr. After the saturation phase, we find L$_{\rm XUV}$
decayed over time by an exponential rate of $\beta_{\rm XUV} =
-1.17_{-0.28}^{+0.27}$. Compared to our inferred age of the system, ${\rm age}
= 7.96_{-1.87}^{+1.78}$ Gyr, our result for $t_{sat}$ suggests that there is
only a $\sim4\%$~chance that TRAPPIST-1 still remains in the saturated phase
today, which is significantly lower than the previous estimate of 40\%. Despite
this reduction in $t_{sat}$, our results remain consistent in the conclusion
that the TRAPPIST-1 planets likely received an extreme amount XUV energy -- an
estimated integrated XUV energy of $\sim10^{30}-10^{32}$ erg over the star's
lifetime.
