Small (perhaps not truly minimal, but small) example to demonstrate:

\version "2.14.2"
\include "english.ly"

notes = { f16 g a b c b a g }

\new Staff {
  <<
    \new Dynamics {
      <<
        { s1\p }
        { \repeat unfold 5 { s2\< s2\> } s2\< s4..\> s16\! }
      >>
    }
    {
      \repeat unfold 6 \relative c' \notes
      \repeat unfold 6 \relative c \notes
    }
  >>
}

3 systems:

1. Dynamics are too far below the staff.

2. Could *maybe* move the dynamics up in the first bar, but it's reasonable to 
have both hairpin pairs at the same height.

3. OK.

Advice? I guess I can make a series of dynamics contexts, breaking where the 
register changes, but... seems rather onerous, e.g.

<<
  {
    \new Dynamics { ... for higher register music ... }
    \new Dynamics { ... switches to lower register ... }
  }
  \relative c'' { ... the notes ... }
>>

Thanks,
James
