I find that you need to look at ripple across a range of timescales,
and if you want reality you won't average or bandwidth-limit the
measurements. Now, if you're preparing marketing material this
may be part of "hair and makeup". But you should look at the
part as its load sees it, not how makes it the prettiest.
Ripple is periodic -if- the design is fully stable, etc. Which is a
thing to be proven rather than assumed. The best performance
to load-step comes at the edge of stability. Subharmonic
oscillations might average nicely to the target DC voltage on
the 'scope but produce significant fsw/2 ripple.
If you want the bad news, try envelope mode and then run
down the extrema.
