It's true to a point. I'll often tune cars to 15:1 or so during cruise. On an NA it's fine, though NOX emissions go through the roof. On a turbo car, you risk melting the turbine wheel...
wow, that be interesting to see.
what would you say is "about right" then for a turbo during cruise?

THROTTLE.
... Throddle: The gas pedal on a toddler's toy car.
As long as you're below atmospheric pressure, the chances of detonation are very, very low. So, it comes down to other factors. On a NA, the major factor is "How lean will it run?" For a turbo, as mentioned above, keeping the turbine wheel a solid is an important factor as well.
