Dear Heikki,
I tested in the same situation, and I confirmed that almost same results are returned.
(results are at the end of the e-mail)
You think that these results are acceptable
because resowners own many resources(more than 64) in general
and it's mainly faster in such a situation, isn't it?
I cannot distinguish correctly, but sounds good.
