total_match_count is used before core.search_get_posts_data event

The core.search_get_posts_data event is provided to modify the SQL query before the posts data is retrieved but total_match_count is used (lines 557-564, 594, & 605) prior to the event dispatcher (line 699). If I modify the sql such that the number of results retrieved is affected, there is no way to modify the total results and pagination.
