yea i don't think there's a set rule. it definitely can invite some skepticism/hole poking around sample bias, etc - but if it's high or it changed to be higher after some company/product change, that's potentially interesting externally (think of it more as an interesting Relative stat vs an Absolute - e.g. quarter over quarter change in NPS or NRR is interesting. Just a single point-in-time NPS score needs a lot more context/comparison/story to be interesting)
If you reframe PR's question to - "what interesting data point/evidence can we cite externally to showcase customer momentum/value?" - then that opens up the playbook on your answer a bit more.
IE if you include some more questions on the survey - there might be some more interesting outcome-based stats to publish from a PR perspective. E.g. from our UE on UE survey. (e.g.. time to value, increase in revenue, hours saved per week, $ savings etc)
