How often do you tune vocals?

[Pharaoh's Curse]

This is a question I have had for some time now and I thought I would ask the studio mixers here.

I see a lot of comments regarding pitch correction / tuning vocals, but how often does it need to be done? How often do you think pro singers have it done? Do you think guys like Rob Halford, Bruce Dickenson, Ripper Owens ever have their vocals tuned?

I honestly don't think I've ever left an entire song's main vocal untuned, aside from acoustic/folky stuff.

I tune vocals more often now maybe just because the projects I work on are more demanding (I am too) and the singers are not great, but I hate it tbh.
