I think Spec would give a clearer picture of what games are being played if it continued to show player match-ups between matches (only disappearing from the browser when a player had declined to rematch). It's not really a big deal and there are probably technical reasons for this being non-trivial to implement..but I think it would make Spectator more polished and easier to follow.
Heck, you could add a status readout to the details panel for each match-up that shows "time remaining: ###", "warmup ##" or "between matches".
