Wemmie's studies have shown that these acid-sensing proteins are required for normal fear responses and for learning and memory in mice. However, while you can buy a kit to measure the acidity of your garden soil, there currently is no easy way to measure pH changes in the brain.
For the normal version of the english typing test we have calculated an average of 41 WPM, this value is based on over 73 million typing results. Considering that these words are relatively easy to type, the avg WPM is probably around 20-25 WPM for normal text with punctutations etc.
In case if you donât know how average typing speed is measured, here are some brief descriptions of WPM, CPM and KPH: 1  Word Per Minute (WPM) is measured by calculating how many words (5 characters/keystrokes = 1 word) you can type in 1 minute. 2  Character Per Minute (CPM) calculates how many characters are typed per minute.
