This function looks more general than its name implies. Seems better
to introduce a function

float
soft_cap(float a, float b)
{
  return (a * b) / (a + b);
}

and then use

soft_cap(dragon[bb].effective_size, 15.0)

instead of

strategic_effective_size(dragon[bb].effective_size)

which is kind of repetitive. Feel free to replace soft_cap with
some better name.
