On climbs with faster group rides here, my little ring may never gets any use at all. When everyone else is standing and hustling up the rollers, you either do the same or get dropped in a hurry. More low- gearing choices aren't there to force us to ride slower, but certainly can allow for a more relaxed pace if that's what we need or want to do.
Usually if I'm going to shift down to the 30, will do it first, at the bottom of the climb, and from the middle cogs. Having the little ring gives the advantage of not needing your biggest cog all the time for climbing; often I climb in 30/19 or -21, which gives a straight chainline and leaves easy-to-shift cog options for adjusting cadence on the hill or when it's time to get out of the saddle.
