Yep that's basically what I do too. Check it's snug. Not trying to drive it on further but just hand right down by the socket on the wrench give it a little push. For 5 rides maybe.
1/20 maybe require this. I also frequently see this failure happen on other people's bikes. Correct installation with attention to cleaning the surfaces, light grease, and adequate torque is the main thing.
I think the reason this advice isn't mainstream is that it isn't viable for a bike shop to do or to instruct. I've lent a wrench out to people that i've rebuilt bikes for with these instructions but it's very tiresome giving customers any instructions or chores unless they're both your friend and a nerd. I'll try to test ride bikes i rebuild a few times to do this but riding the very small ones sucks.
