It's not even about the time, either. I do my best work in the morning. Almost every morning on my last project went like this: Get into work, grab a glass of water, bring up my todo list, start polishing off the first item, make 5 minutes of really good progress and the bam, standup. The comparison isn't between the benefits of a good standup and nothing, it's between a good standup and whatever productivity you lost by interrupting the entire team (same as any meeting). You need to make sure it's worth it.
