I believe the show has remained an easy rush. From what I understand, especially when it gets a few hours away from curtain, they start selling tickets to rush that haven't been sold by the regular box office yet.
To answer your specific question about the weekdays, I rushed this show (for a second time) on a Wednesday matinee about three weeks ago, I believe. we arrived at the box office maybe at around 10:00, and we got five tickets. Four were together in pairs on the extreme sides of the orchestra section, and the last ticket was in the front row, center orchestra. I had sat in the front row before and loved it, but I wanted to give that seat to my friend, so I sat on the extreme left of the orchestra, in the fourth row. Both views were fine, in my opinion!
Hope you enjoy the show!
