Focus to infinity?

Depth of field tables help but they do not tell the whole truth.

Only the point you focus on is actually in true focus, focus then falls away in front of and behind that point.
Depth of field tables show you where it has fallen to a just about acceptable level.

Better practice for most subjects is to focus in the area of most importance. Other points will be less sharp but acceptable in line with the tables suggestions.

Most general landscapes a focus point around 30 or so feet away works quite well with an aperture of F8 and a normal to wide lens.

But it is dangerous to rely on hard and fast rules.

Experience will eventually be a better guide.

Nope you are wrong. the C of C remains constant until you reach the limits of your DOF, then it starts to fall away. That is why when you do a calculation for hyperfocal, the larger the C of C the lower the hyperfocal so the greater the DOF.
