Does "there was no calculation" refer to "there was no (our) planning"?

Context:

[Matt Dayton] "Okay, I would like to echo a frequently asked question on the NIST.com website regarding World Trade Center 7 in that the report on World Trade Center 7's ___ after collapse has not been released by NIST. And the fact that the tower collapsed in approximately 6.6 seconds, and free-fall in a vacuum would be approximately 6 seconds, is a controlled demolition hypothesis being examined for World Trade Center 7?"

[John Gross] "We are looking at it. There's actually a very good write-up recently from Controlled Demolition Expert which you probably ought to read. We haven't finished the investigation yet, so I'm not at liberty to talk about any intermediate finding. We were charged with finding out the cause of the collapse. And we found what happened. I think we've scientifically demonstrated what was required to initiate the collapse. Once the collapse initiated, the video evidence is rather clear. It was not stopped by the floors below, so there was no calculation that we did to demonstrate that, what is clear from the videos."
