For vertical alignment purposes it's convenient to have uppercase characters aligned to the middle of the text line. For that, descender metric should be equal to (ascender - cap height). This is also a recommendation from Google Fonts: https://googlefonts.github.io/gf-guide/metrics.html#9-uppercases-should-be-centered-in-the-text-line
In Commissioner, the metrics are:
Ascent: 2034
Descent: -412
Cap height: 1426
So the gap above the top of uppercase characters is $2034 - 1426 = 608$ units, but the gap below is just 412 units.
I suggest to increase descent, decrease ascent, or both.
