So which of the above figures would be regarded as the cut off point for when something is regarded as extraneous?. There is quite a gap between 7.67 and 22 Kohm.You would get 7.67k ohms with the calculation given. It's just that the calculation we generally use includes taking off 1k ohms for resistance through the body. Hence 22k rather than 23k, or in this case 6.67k rather than 7.67k.
