Nobody here can predict what will happen in August. In any event, schedules that far out are notional in any event. Your one hour may drop to 30 minutes or increase or one or more of your flights may be cancelled.

But, presuming that the schedule sticks, the issue is not so much whether you can make the connection, but the consequences if you do not. If you misconnect, your onwards connections are not good and certainly not in D1.

I would allow the 3 hours against spending a rotten(er) 10-hour flight + additional connections + further delays. You should also understand that you may be forced into the lousy choice of waiting around for the next day's flight in D1, later flights in any class or worse flights in F.
