It's all helpful, though it can hardly convey the atmosphere of the event.
There are lots of interesting nuggets; for example, M'balia Rubie, the teacher who said (p. 141 of PDF) she couldn't prioritize traffic and shadows over jobs and housing, signed in (p. 7 of PDF) as a member of the Downtown Brooklyn Neighborhood Alliance (DBNA), a signatory to the Atlantic Yards Community Benefits Agreement led by the Rev. Herbert Daughtry, but she wasn't announced as such nor did she make it known.
As for the Rev. Daughtry, when he got the 20-second warning (p. 133 of PDF) you can see that he continued for quite a bit. I clocked his speech at 5:45, albeit with interruptions. After the hearing, the ESDC changed its policy at the two follow-up community forums and cut the mike for all speakers at 3 minutes.
