By the way, this wasn't even the final battle.
So, is a four-hour battle considered normal? If so, what's the point of timers if we're essentially giving the opponent unlimited time to think? After all, there are also very challenging battles against neutral creatures, where, apparently, it's also acceptable to spend four hours.
It seems to me that there's some kind of inconsistency, not necessarily between the SOD timer and this situation, but even between the WTS timer and a four-hour battle.
I'm not saying that the final battle should be of poor quality, but how can you stretch five rounds out to three or four hours – I just don't understand. I've never seen or heard of battles like that. If you've heard of them or participated in them, I'll accept that high-level players can have battles with an opponent that last for four hours (or even six or seven, if the other player is equally "thoughtful").
