this is nepc survey done in 2021. so, this is a smaller set then noserman survey. >> i say this sample size is statistically insignificant but given to us a reason to do this. those are things i have problems with. the more important slide perhaps is couple pages before that, where it showed how many of the funds are actually doing this. i think that is page perhaps 27. sorry, my pages got mixed up. in terms of best practices, percentages, my concern about proving the case is how did they do what they are investing, opposed to quhoo made the decision? i know many endowments are much more successful invest rs then we are. there is a lot of things we have been doing a long period of time our peers do not do. is that return best practice to invest in or not. others with their decision people process, so many do it it must be best practice and i would say that is not true. if we get numbers in the top quartile and haven't been doing it, is it our process or not? at the same time, trying to figure can we improve the proces
