Not sure whether there is a problem with the bidding or just the tooltip (nevermind the problem with my chronic overbidding), but when you hover the 3H bid made by GIB, it indicates 6+ hearts and 11+ HCPs. Obviously GIB had neither. Was GIB just feeling frisky, or am I reading the tooltip wrong?

The explanation is correct. Just North simulated to bid 3♥ instead of pass ( which are both considered before to pick one ).

The pass seems correct, but in this case the percentages draw 3H probably.

Also, it says 11 or less HCP and 11-12 TP not 11-12HCP. GIB has 10TP in its hand here.

Note that you are expected to make a support redouble with 3 hearts, which is why the explanation of North's 3♥ bid specifies 6+H. But I agree with your bottom line that GIB's bids should match their explanations.

It appears to me that 15 out of 15 Norths who faced this same decision chose to bid 3♥. If GIB would "always" bid 3♥ in this auction, the description should say "5+H", not "6+H".

If you give a support redouble, GIB bids spades which is incidentally explained as including 4+H.

The 3♥ without support redouble is certainly bid needing 6cards in the hearts. The problem here seems to be the simulation result pretending GIB having more then it has. 1 heart and 1 tp off. GIB is not supposed always to bid 3♥ here, even it would rarely pick that bid, especially without support.

You mean that if you rebid redouble, North will/might/should bid 3♠?

It means he bothered to look at the auctions held at the other tables, instead of making up an answer, and he observed that whenever South redoubles, West bids 2♣ and North bids 2♠ (not 3) to show invitational values.

But, based on the available evidence (15 tables), GIB does always bid 3♥ here, and this is what OP is complaining about.
