I just took another run through the linked video.
If you primarily play in isolation, this may be something you want to consider.
If you play with others, remember that they will probably be in different temperaments. In addition, using "pulls" and "slides" will change the temperaments. Others may be slightly out of tune by a few cents on one string. Using a electronic tuner for each string will give a different temperament than using the tuner on one and doing the others by ear.
As a former physics major, I find it interesting. When I'm a player, I use the tuner to set my bass string, then go by ear or trust the 4th fret.
I believe that the richness of an orchestral sound comes from the instruments being slightly out of phase and precise frequency.
If you want to re-fret one of your instruments, the spacing can be determined with
