Hi DT,

Thanks for the input - I'll have to look at it later with some of the other suggestions I received. My brain is too fried right now...

  Dennis,
  The 4 last peaks of H [for per=10] are

  per=10;
  //Plot(H,"H",colorBlack,1);Plot(Zig(H,per),"",colorYellow,1);
  Title="";
  for(J=1;J<5;J++)
  {
  X=ValueWhen(PeakBars(H,per)==0,H,J);
  Title=Title+"\nH"+WriteVal(j,1.0)+"="+WriteVal(x);
  }

  Their average will be
  per=5;av=0;j0=4;
  Plot(H,"H",colorBlack,1);Plot(Zig(H,per),"",colorYellow,1);
  Title="";
  for(J=1;J<=4;J++)
  {
  X=ValueWhen(PeakBars(H,per)==0,H,J);
  av=av+x;
  Title=Title+"\nH"+WriteVal(j,1.0)+"="+WriteVal(x);
  }
  Title=Title+"\nHav="+WriteVal(av/j0);
