This is a minor irritation but needs fixing as information presented to us is misleading and misconstrued at best.

At the end of a round, BBO presents us with something like this:

Round 9 or 10 complete
9 tricks taken +100

It should say:

Round 9 or 10 completed

Then for us, because they were in 4C making 9 tricks, it should read:

4 tricks taken (+100)

And for them it should read:

9 tricks taken (-100)

If above is too much to code, then something like:

9 / 10 tricks taken (-100)

IOW, seen from the declarers POV, defenders will have to adjust.

It's still less confusing than current version which says, in effect, declarer was one down but still made a plus score. First suggestion leaves no room for ambiguity.

I agree, this is one of the many approximations of the original BBO interface that has never been improved (although "9 of 10" is much clearer than "9/10").

Bridge scoring is based on the number of tricks declarer took relative to the contract's requirement. This is the first I've ever heard that someone was confused because the number of tricks reported to defenders was not the number of defensive tricks.

I think only a beginner could be confused by the number of tricks taken, even if the message did not say which side took them.
But not mentioning the contract requirement or the relative number of undertricks/overtricks is already unusual.
Not specifying whether "+100" is relative to us, the Declarer or NS is gratuitously confusing IMO.
