30% Favs have been getting up ever since records have been kept .

One could argue 30% are rigged ,
30% Favs get up ,30% true form mules get up (other than fav.) ,10% "hows your father" "how did that get up" ?.

At the end of the wash up those stats repeat year in & year out, for the last 50 years.

In between all this, there is a profit to be gleamed.
