It is not mine, but gautaml's one, and it use the independent tool of chrome that perform the same test. But when using the webservice it shows different results.
Are you sure they perform the same tests though? Why would Google build a Page Speed Chrome extension if the exact same algorithms were already built in? I suspect they are working towards the same goal but are approaching it differently.
I just found it funny that the web gave google.ca 100/100
