I love my DA Mask. Awesome can. CCI standard on any host makes for an excellent quiet time plinking.
Cci standard is technically subsonic at 1070fps. Speed of sound is a little over 1120fps
to be marketed as subsonic they usually are under 900fps or .8 Mach
biggest variable for speed of sound is temperature.
@90deg speed of sound is 1150fps
@0deg speed of sound is 1050fps
cold air be more dense.
those numbers are for dry air.

Yeah I've never had CCI standard go supersonic. Never even in 16" barrels. Most of the time bulk cheap ammo is still subsonic on my Ruger pistols suppressed. You'll get a few that go supersonic but a lot stay subsonic in 4.5" barrel'd 22 pistols.
