Over one minute of diconnected gameplay. Interesting.
This could allow for small bumps in the connection. However, the queston remains whether you have some sort of allowed timeframe in which you have to reconnect or whether Neal just happened to disconnect between two connection-checks by chance.
In the first case this would allow for smaller hickups in the internet connection.
The second case would not, as it would be possible to lose connection just before the next check with the UBI servers is due, which could stop your game.
Sadly I don't see UBI revealing such information anytime soon as they might consider it confidential ...
