These methods allow you to probabilistically reuse data rather than making a fresh record every single time you fabricate.

  if model_klass.where(attrs).count == 0 || die_roll(model_klass.where(attrs).count % 5)
    Fabricate model, attrs
  else
    model_klass.where(attrs).offset(rand(model_klass.where(attrs).count)).first
  end
