Nice arrangement and approach to solving an elusive, hard problem, or more accurately, estimating a physical parameter more precisely.
Quantifying neutrino mass more precisely will lead to other adjustments in stellar masses and energies? I would think so.
The following article says recent observations and calculations indicate neutrino masses are even smaller:

I wonder if the incredibly small masses can be considered to be part of the “fine tuning” problem.
