Dear Ronz, 
 
 In regards to the Wiki, Multi-stage Fitness Test page, I have undone your edit due to vandalism by unknown users and this revision including irrelevant embedded links to commercial References within the text, in an effort for Search Engine Optimisation. There were also various typos and incorrect information about Digital Audio in the version. 
 
 As with the other External Links such as TopEndSports.com, the link to PFTests is for a free Bleep Test Training Program, Bleep Test information Booklet and a Bleep Test information Blog, which is relevant to the Wiki Multi-stage Fitness Test page. PFTests is registered with the UK Fitness Industry Association (FIA) and the Register of Exercise Professionals. 
 
 If you’d like to discuss the changes please do not hesitate to email me back. 
 
 Kind regards,
