I have no background in statistics, but that may be to my advantage here. Doesn't keeping confidence intervals vague in the same way keeping estimates vague help? "Yes, I think it's a minor change. Almost certainly done by the end of the week, or else we have bigger problems." "I don't know what this entails. Looks like it could be done in a day, but I wouldn't bank on that unless I can spend an hour investigating." "This is a large feature, but nothing seems terribly complex. I think it's one or two weeks, but we should be ready for it to get snagged on small defects. We should leave room after the release for a rapid followup patch that may be needed."
