Sorry, I mean..
Derivative component becomes something like Td.s / (1 + 0.1 Td s)

So a first order filter with one tenth the time constant of the derivative.

Maybe he has DSmoothing := TRUE?

From memory this adds a filter of 1/10th your derivative time constant to your derivative term, but I couldn't find the reference to this calculation.
