I do not see how can you get this conclusion.

How do you know that the difference between
shredder8 A1200 and shredder8 2800+ XP is 100 elo against humans?
Maybe it is only 40 elo.

Assume that you are right that shredder on A1200 is weaker than 2800.
How do you know that the ssdf list is also inflated for engines of 1999.
Maybe it is only inflated for engines of 2004?
