Hi all:
It appears that the Pickit2, if left connected to ICSP pins and a PC USB does influence the results by introducing some type of noise to 16F adc sampling
My experience was for 8 x 10 bit ADC samples summed and divided to 11bit accuracy for voltage accuracy to 2 dec. places. The Pickit2 connection created a noise of up to +/- .08V in the result.
Took a while to trace it down , but pulling it off the ICSP immediately stabilized the readings.
