For this reason, I feel that n>~1EEX7 should not be accepted in the WP 34S , the CASIO 9860gii, and on the Prime.

Yes, there are some issues with the Binomial and Poisson distribution, probably caused by the underlying Incomplete Gamma and Beta functions, cf. for instance this thread. I hope that sooner or later there will be an update. Pauli and I have been discussing this some months ago. But it seems to take its time – Pauli is very busy, and I'm not sure if the cause of the Beta/Gamma problem has already been found.
