Twitter speed

I would like my twitter client to come with twitter speed numbers. I would like to know how fast my Timeline is moving in terms of tweets per hour. How fast my @mentions are moving. So then people would recommend say to get an ex number of people you follow until you reach a certain Twitter speed and then stop because otherwise you can’t possibly keep up. @mentions feed speeds would also be a measure of relevance of whatever it is you are tweeting.
