Pro Day numbers

A few UCLA players remarked at the large number of NFL scouts out today. I was told the official number was between 30 and 35.
Here's some 40 times from some of the players out there:
WR Brandon Breazell was timed between 4.29 and 4.39, depending on the stop watch holder
DE/LB Bruce Davis was in the 4.6s
CB Trey Brown was in the 4.6s
WR Junior Taylor was in the 4.6s
Dennis Keyes was in the mid 4.5s
OL Brian Abraham was in the 5.1s
OL Noah Sutherland was 4.96
DB/KR Matt Slater was 4.41
CB Rodney Van ran in the 4.5s, but said that was the only part of the workout he wasn't happy about.
