Assuming a 15 minute quarter(though most Madden games have shorter quarters, especially if they're multiplayer), to get 255 points in a quarter, a team would need to score a touchdown + 2 point conversion every 30 seconds. For a full game, that's every 2 minutes.

Any given play generally takes 10-20 seconds, and you're going to be running, bare minimum, 2 plays per 8 points(1 for touchdown, 1 for 2 point conversion). So that's about 25 seconds per score.

If the teams are remotely well matched(i.e. aren't a Breaking Madden team), they'll take at least 2-3 minutes per possession, since you're most likely going to have 4 downs, which have a play clock of 40 seconds(most teams use around 30/play), so the "average" shortest possession is something like 2 minutes.

The point of all this? The Breaking Madden games are really an outlier that you'd have to specifically code for.
