You've forgotten to login again. I don't agree that Speedometer is a good name for this module it does not fit any of the naming convetions or logic layed out in the examples you've been given links to, or reflect what a speedometer does. I think you've totally missed the points made about naming.

Also to use this I have to write a script which uses your module, why not just make your tool the script? None of this seems make life any easier. Did you read any of tyes posts on the subject of Benchmark? None of this seems any easier to me. Also your Changes file is still wrong, and your POD is not formatted correctly.
