I don't have measurements for the latter - and the former is in
the public domain.
...

1. Everything after 16 was 'straight-lined', which is wrong since incremental 
MIPS are not linear.
That used to be documented on the LSPR Site; I don't know if it is still.
Plot the numbers; you'll see.

2. A new workload was added to the
z/990 mix that was never calibrated on the z/900. So, how can you consider its 
measurements to 'speak for themselves'?

3. A workload was dropped from the z/990 mix. Same question.

In what I laughably call my mind (and in the opinion of a few others) this is 
incomplete analysis.
I do not trust any figure over 16 CP's.
Given the above, how could anybody?

(PS: I'm not giving away any IBM secrets. The above three statements are 'in 
the public domain'.
You just have to read the documentation.
I performed my analysis without access to any internal documentation, after I 
left IBM.)
