żeby podsumować Anglais:

to sum up, we may state that...

This house was, all in all, a great investment.

I've been following the election campaign and all in all I think the goverment will win the election.

Sure, it rained on our vacation, but all in all we had a great time. All in all, the team has a bright future, even though they didn't make the playoffs this year. All in all, it was a very good party.

I've seen Jeff and you, and I let this guy beat me at golf, so all in all it's been a pretty good trip.
