Believe it gradually drops off, but you are inline for the average life expetancy. Having the EGR deleted will help as the EGR increases soot production, as will the type of driving you do, more city driving will be worse than motorway.
You can get stuff to put in the fuel tank which helps burn off the soot in the DPF, which may/ may not increase the life expectancy (certainly reduces the built up soot).
It's likely the removed DPF was power washed, when I took my old one off it was covered in soot that came out all over the place.
