Average Posts Per Day in 'profile' AND 'mini-profile'

[M³]

Hey there,

I went through the index to see if there was an 'Average Posts Per Day' type plugin and did notice the 'bar' one, but I'm looking to see if someone can make one that simply shows an 'Average Posts Per Day' with digits/numerals -- IE, 3.5 posts per day.  If possible, I would like to have it shown in each member's profile AND mini-profile, most importantly. 

Thank you, kindly.
