Answer 1

for rating count in layered navigation it will count the number of rating of product is above 80 and less then equal too 100. hope you will find the solution..

 protected function _getCount()
{
    // Clone the select

   $select = clone $this->getLayer()->getProductCollection();



    $pid1=$select->getAllIds();
    $var=100;
    $secondvalue=$var-20;

 $products = Mage::getModel('catalog/product')->getCollection()
            ->joinField('rating_summary', 
               'review_entity_summary', 
               'rating_summary', 
               'entity_pk_value=entity_id', 
               array('entity_type'=>1, 'store_id'=> Mage::app()->getStore()->getId()),
               'left'
            )

            ->addAttributeToFilter('entity_id', array('in' => $pid1))
            ->addAttributeToFilter('rating_summary', array('lteq' => $var))
            ->addAttributeToFilter('rating_summary', array('gt' => $secondvalue))->load();



    return count($products);

}
