It won't be always nor repetitively (due to recursive games), but still makes sense. Back to the start point, 40 times a day is quite high. Here are numbers from yesterday's voting statistics (voting weight considered).
N: 2675 (voters)
Mean: 23.0
Median: 9
Mode: 1 (415 voters)

It seems 5~20 votes per day is human-friendly number. I think I am very active human voter but only does 24 times yesterday.
