I only have one "1st hand experience", and that was sort of 2nd hand lol.
@DHuffman shot his 12 shot tuning ladder through one , but on paper as well. The take away I had was it's close, but not close enough. If memory serves, 2 shots were close to an entire bullet hole off, some quite precise, and the rest only slightly off. Although the group size was similar enough for testing loads. I also noticed all the error was plotting them favoring them being closer to center than actual as well. I literally stop looking when I see screen shots posted, or whatever that's called. I guess I prefer holes as well, but if you got guys willing to attend then great. Hopefully people will have both, and basically by default do a study over a season on just how precise they are now.
