I read each one the day after the meeting and combine those that are the same or very similar.  So I basically narrown them down to 1 to 2 focus points.  I then use those similar responses to determine if I didn't explain something well enough so need to review or if I explained good and more info is requested.  I then will factor that into my next several info minutes and/or plan to expand more on my next 7-minute presentation.
