The audio recording of the Michael Brown shooting proves Darren Wilson's story is false

To summarize: Wilson claims that Brown was charging toward him, that Wilson began to fire his gun when Brown was about 15 feet away, and that Brown continued to advance without slowing down until the final gunshot stopped him.
Is there an objective timeline of these gunshots? Fortunately for us (and unfortunately for Wilson, had the prosecution actually been interested in prosecuting the case), there is. A nearby resident who was in an online voice chat at the time obtained audio of all the gunshots fired in the street (that is, the two gunshots that occurred at Wilson's SUV were not included). Here is a visualization of the recording:
We can see that six shots (marked in red) were fired within a span of approximately two seconds. There was then a three second pause before the seventh shot was fired. The eighth shot came one second later, followed quickly by shot 9 and then shot 10. The total time was 6.572 seconds.
To reiterate, Wilson claims that Brown was charging toward Wilson throughout the time that Wilson fired these shots. It seems a fair assumption that Wilson's use of the word "charge" would mean that Brown was sprinting. How much ground can a sprinting human cover in 6.572 seconds?
Let's start, just for curiosity's sake, with the fastest speed ever recorded for a human on foot: 27.44 mph by Usain Bolt. At that speed, Bolt would cover 264 feet in 6.572 seconds.
Obviously, Brown wasn't an elite sprinter; he doesn't look to have been much of an athlete, period. So let's try to get a more realistic estimate. Your average human isn't going to have a record of their sprinting speed available. One place where humans are regularly recorded sprinting short distances is the NFL combine's 40 yard dash. In 2014, the fastest 40 yard dash time was running back Dri Archer's 4.26 seconds; the slowest was offensive lineman Cyrus Kouandjio's 5.59 seconds. Kouandjio's listed measurements are 6'6", 311 pounds, so he's of similar proportions to Michael Brown's 6'4", 292.
