Clearly there are several camps. I own 4 torque wrenches...
I have a reasonably well calibrated elbow having been doing this stuff from the age of 4 but there is no substitute for a torque wrench if you want to push the envelope of possibilities.
On dad's racing engines we did a lot of destructive testing and assembly-disassembly to see what we could get away with. One of the things that was done was helicoiling all 10 studs right from the off.
The findings on non helicoiled were simmer to the higher end torques above.
On my ruby I went with the torque wrench and the manual. I don't know the provenance of the studs or the material they're anchored into so discretion is the better part here.
