Do an experiment. Type a key - like the letter A. How often do you have to press it until you get something that is not the letter A?
I've been having a hard time with my keyboard, especially with using my number pad in Calculator. The error rate seems to 0.2-0.5% (2.9 sigma), switching the mode from Decimal to Octal randomly but with consistency. The space bar in most applications has a rate around 0.1%-0.2% (3.1 sigma), switching the space for a three.
I'm thinking of getting a new keyboard but should I be expecting a 3 sigma rate or should it be higher, like 4 or 5 sigma for good keyboards?
