    Average speeds are more commonly used but can give a wrong impression of the actual user experience since fast connections can bias the average results. Median results represent the point where half the population has faster and the other half of the population has slower data transfer rates.

    Some of the main modifications were an increase in the power supply to guarantee a speed of 12 knots (22 km/h; 14 mph) and a change to the angles and lines of the hull to improve steering. Another significant change was to raise the top of the anti-torpedo bulge above the waterline and reduce its width; both changes would improve the stability ...

    Blücher increased speed to 32 knots (59 km/h; 37 mph) in an attempt to get past the Norwegian guns. [14] The 15 cm (5.9 in) guns on Drøbak, some 400 yd (370 m) on Blücher ' s starboard side, opened fire as well. [23] At a distance of 500 m (1,600 ft) Blücher entered the narrows between Kopås and Hovedbatteriet, the main battery, at Kaholmen.

    With the onset of the era of desktop computers and smartphones, fast typing skills became much more widespread. As of 2019, the average typing speed on a mobile phone was 36.2 wpm with 2.3% uncorrected errors—there were significant correlations with age, level of English proficiency, and number of fingers used to type.

    With this speed, the Yamato class' ability to function alongside fast carriers was limited. In addition, the fuel consumption rate of both battleships was very high. [ 60 ] As a result, neither battleship was used in combat during the Solomon Islands Campaign or the minor battles during the "island hopping" period of 1943 and early 1944. [ 60 ]
