This seems to be a bit less than I would estimate taking the average of all
increases from P90->P200MMX, or do you think it is more than 100%?
In general the increase is between 50 and 80 pts from P90->P200MMX

Or 25-40...

So in this case, do we assume Shredder3 being equal to Hiarcs7? If so Shredder3,
running on the faster hardware, should get the 53-54%, at the moment he even has
no 40%. Or does it count into the margin of error?

Oops. Ignoring means that Shredder3 should/would perform on a MMX166 like on
that K6-200??
I don't think so.
