TheBeak - some points for you:
Why am I supposed to say sorry to you for pointing out that you exaggerated a drop of 21 points, claiming it to be 40?
There is no such thing as parallax error on LCD screens - the error is in your wilful misreporting. Since when did a drop from 4120 to 4100 represent a drop of 40? As I said, maths, observation and accurate reporting clearly aren't your best subjects.
I hadn't considered myself 'your friend' on the basis of this exchange. There is no need for your patronising tone.
Possibly best summed up by Alex W when he said to you:
Absurd. Get a life.
