Need to get old sum before new vote is set

There is a way to get the old "sum" value before save ? I need to calculate something and i need both the old and new sum values.

Something like (sum before vote was 8 , sum after vote is 9).

I tried using hook_votingapi_results_alter() but the $vote_results contains only the new data.
I have tried to receive the old data by making querys in votingapi_cache table but with no success. Maybe the data was already gone at that point.

function module_name_votingapi_results_alter(&$vote_results, $content_type, $content_id) {

  // get new data
  -  $vote_results provide the new data. All good.



  // get the old data
  -  query to votingapi_cache return nothing all the time
  -  tried using votingapi_select_single_result_value() but again it doesn't return anything


 }

Is this posible ?

Thank you.

EDIT:
solved using vote up/down api
