He gave 10 strokes before he put in the tube and then 25 strokes more. 10+25=35 stokes.

I don't believe the tire was correctly inflated with so few strokes. Also, in my experience, when re-fitting the tire it is best to turn the bike upside down so one can center the tire properly, especially if the brake pads are not even. Obviously excluding the time to hunt down the source of the flat will decrease the time; however it is not a very smart way to replace a tube. Could be a staple or pin that will just zap the new tube.

The clip is called: "Changing rear flat on bike" (not innertube) and that exacly what he dig, he had a flat tire, put in a new tube and soon he will have a flat tire again ;)

What kind of a frame-fit pump can inflate a tire in 25 strokes? My Blackburn pump takes at least 35 strokes. What is the PSI of this tire after inflation? I hate to deflate your accomplishment, but that's my criticism ..
Yea but did you find the wire stuck in the tube? Sure you tried to slice open your hand but if the wire "RETRACTS" into the rubber of the tire or if it is a small "sharks tooth" of glass... You just had another flat somewhere around 5 miles into your next ride... :)

This demonstration was done in response to a challenge that specifically stated that finding the source of the flat was not part of the timed process. You are, of course, correct that finding the wire or glass or whatever is part of changing a flat in real life. However, it would be impossible to standardize the cause of a flat for the challenge, so it was excluded. The source of this flat was my index finger on the valve.
