Please fix ignore percentages

Ross is now showing 110%, which is proof that the percentages are incorrect. Under "Who am I ignoring" he is listed as someone who I ignore while I am actually not ignoring him. In the past I have once ignored him for a week or month though. It seems that this information is not correctly updated. My conjecture is that when you temporarily ignore someone, and you let the specified time pass without actively un-ignoring him or her, it will still count as an ignore in the numerator of the percentage, but not in the denominator.

It would also be nice to know what the denominator of that percentage actually is, and to know the total number of visitors of the forum on a given day or moment.
