Congratulations on getting the traps finished. Looking forward to the pics.

I wouldn't bother doing another graph after treating the first reflection points -- while the treatments are likely to make a difference, it's not a difference which will really show up on an FR graph.

There is no substitute for a group of acoustically insignificant assistants (aka kids) running in and out with the treatments while your eyes are closed.
