It more or less seems from some of the above and related posts that revs are often assessed by sound, which can be misleading.
Most owners decide some real or theoretical speed in top which they consider reasonable revs for their car to sustain. Without the need to know the actual revs, the equivalent speeds in the gears are quickly calculable from the gear box ratios. These speeds can be recalled for sustained hill climbing. The easy to remember 10, 20, 30, 50 is close to one grouping for the common 4 speed box.
