Stackoverflow API - get the "received" number of user polls

I am currently using the Stackoverflow API to get a list of detailed user information (via http://api.stackoverflow.com/1.1/usage/methods/users-by-ids ). There is an attribute called "up_vote_count" that returns the amount during which the user has GIVEN upvotes. What I want is the opposite:

Is it possible with the Stackoverflow API to get / count the number of ways that the RECEIVE user is growing?

The only way I've seen is to scan reputation changes through http://api.stackoverflow.com/1.1/usage/methods/user-reputation-changes and add +1 to the upvote local variable if there is a "+10 reputation". But that would suck a lot ...

Any ideas?
