Agreed, and maybe this is more common than may impression & experience, but if that's the goal, wouldn't you prefer to do it in the afternoon? After you've spent some time on something, but perhaps still have some time left to shift approach or have a 1:1 call with someone who says they can help?

Sometimes stand-up for me means 'remind myself what I was doing'; if not that then I've certainly not got far past it, haven't had long to get much done or be stuck. I'm unlikely to say in a stand-up that I'm stuck on something, I'll have a(nother) crack at it and perhaps ask after lunch if necessary.
