After 4nt as RKCB,Gib N answer is 5♠ !
Actually I hace trump Q,why 5♠ ? Usually it should imply extra lengths in trump ♥,I still know Gib N have a K in some side suit at least,so I have sufficient reasons to bid up to 7NT.
If Gib N answer is 5♥,how high for me? What's the reasons of 7NT?
5♠ is praiseworthy.

The reason for 5♠ is that last version v30 contains some "6th sense" for GIB.

Over 4NT if GIB sees there are 10+ trumps it would reply about having queen of trumps which very likely will drop.

split for 3 missing cards is

78% 2-1
22% 3-0

And as the extra trump length is not always clear, these 1,2,3+ trumps would be equivalent as queen possession.

Sorry,I can't totally agree with what you said 6th sense since it is a right descriptive bid.

Please look at another evidence hand.

After 4nt,how to tell me extra trumph length and values?
5♠ is just a decent reply since we have no more space,so I think 5♠ still is a commonese bid with 5-card trumph support.

I have to say this is a praiseworthy bidding.
