Ok, criticise the precision of your PCs, but do you have any idea how precise is your tuning fork ? I have found on the net that a steel tuning fork can be as precise as 0.05 Hz while an aluminium one would start a 0.2 Hz, quickly degrading to 0,5 Hz I think a PC with a common soundcard, playing a calibrated wave file is ... not to be compared with a steel fork, but probably as precise as a common aluminium fork... If you use tune lab after having properly calibrated it, then it can be as precise as a steel tuning fork.
