ThnD::GetRandom() in high dimension

Hi experts, I and filling a 4D ThnD with my data (4-element vectors), and draw new samples out of the histogram (realizing that ThnD has GetRandom() method similar to TH2D and TH3D. The method did produce the marginals and the pairwise relationship between the variables.
I am just curious that is there anyone who use this for dimensions > 8 and with success ?

ROOT Version: 6.24.00 (conda)
Platform: centos7
Compiler: gcc9


Thanks for sharing this interesting use case.
We are not aware of experiments using the feature in such an extreme use case.
As you imply in your post, it works, however it is not optimised for such dimensions.
