As part of a current experiment, I'd like to be able to provide feedback to participants about how fast they were at the end of their session. Ideally, I'd prefer to display their average reaction time on the final screen, but I'd be content to just display the total time for the experiment as well. Can anyone think of a way to do it? Maybe using a meta command?

(The point of this is to allow RAs to quickly ascertain roughly how fast participants are going without having to open another program.)
