I don't see how the autoscale could have any effect at all on how long
it takes for a drift to start. It can cause the displays a little bit
longer to scale the data properly, because the new scaling is more
sensative to small errors in the sky finding, but even if the sky is
above the top grey level used by the display (in which case the displays
will show up as solid blue), the data should be just fine.
Therefore, if the reason you called the data bad is that the screens
were blue, I suspect the data was really just fine.
