appearently not. I just make a simple change

        d_next_input += ii;     // update for forecast
        return ii/DEC;               // no work completed so far
      }
    }
    // no non-NORMAL tag found
    d_next_input += ii;         // update for forecast
    return ii/DEC;                   // no work completed so far


with ii/DEC instead of 0, and was rewarded with:
