Averaging AtoD samples

[HankMcSpank]

An old thread & just revisiting this issue again ...re the spurious rejection, there's a setting as follows....

Reject          CON  2          ' Spurious Rejection level

Presumably that setting is the amount of samples, before the averaging code accepts/adopts the new incoming sample (vs just throwing away a sample that diverges too much) ....but what is deemed a 'spurious' sample ..in other words what in the Darrel's code a couple of posts above decides that the incoming sample was spurious ...and can this 'sprurious diversion amount' be adjusted?

To help explain, consider the following trail of ADC samples...

99
101
100
91 ------ not spurious, just a low sample
97
101
50 -----------spurious
98
100

How is the spurious rejection set so as to accept the ADC rsample of 91, but to just reject the sample of 50?
