i) This is a matter of taste. I prefer new content to be at the top of 
a post as I'm not a goldfish and usually can remember the previous 
posts. Any quoted matter I usually include for newcomers to the thread 
- except when replying inline as I am here.

ii) Do as I say, not as I do?

iii) Or is this a deliberate wind-up?

867 MHz.

Having searched online, the speed as given by sysctl (533 MHz) has been 
attributed to PMU problems and faulty sysctl behaviour - although this 
has all been from non-expert speculation / trial and error.

I found one post where someone had got an incorrect value and run some 
benchmarking and then a correct value (reset PMU) and repeated the 
benchmarking. The benchmark results did not seem to be significantly 
different either way and so I'm assuming that this is a sysctl artifact 
- although some confirmation from elsewhere would be neat.
