При увеличении временного интервала наблюдается расхождение в подсчёте баллов: в актуальной версии геймификации такие показатели, как время чтения и количество прочитанных постов, округляются ежедневно, тогда как данный запрос суммирует все значения, включая остаточные части. Тем не менее, этот запрос весьма полезен для проверки того, как изменятся ваши настройки начисления баллов, без необходимости пересчитывать все текущие баллы на сайте.
Также в запрос не включены пользователи из группы @staff, хотя это легко исправить, если вы захотите это сделать. 
В зависимости от размера вашего сайта, возможно, потребуется сократить временной интервал или сузить круг целевых групп, чтобы запрос не завершался по тайм-ауту.
