Hard to say what is still making sense today. That Random typos are ok with 10% but Im not so sure about the "character spinning". It might look odd for G. when it sees that.
I did checked typos with various parameters 10%/20%/50%/70%/90%. But no any effect in my verified articles. Please Can you elaborate me how functioning typos????
well there are many ways to generate typical typos:
One is by using the next character around the one you want from a normal keyboard. Another is typing the same character twice, or leaving away one Another one is to just mix upper and lowercase in case one word starts with an upper case letter and the next char is also upper case as the user was not releasing the shift key fast enough.
Such things are "simulated" here. If you use 100% then many words are typed incorrectly. Well thats all I can tell you to this function.
