So x1 is a number, probably a {ni} in most cases, x2 and x3 are the same as for {fadni}, x4 probably talks about how statistics were obtained, maybe something about how {ni} were assigned, if that is not obvious.
So: li reno cnano le ka ce'u mitre makau kei lei vi tricu 20 is the average of how many meters they measure for these trees. Something like that? How would a {ni} work in x1? mu'o mi'e xorxes _________________________________________________________________ Get your FREE download of MSN Explorer at http://explorer.msn.com/intl.asp
