[CUWiN-Dev] question about HSLS

[=?EUC-KR?B?wNO/tbrz?=]

Thanks to your advice, I've got etx values like below. But a strange thing
is that the values are sometimes much larger than the average, for example
554 or 1369.
Actually I put two nodes closely (about 1 meter distant) using a clear
channel of 11a, and ran HSLS only these two nodes. And I assumed that real
etx values are calculated by dividing the etx values obtained by 256 as
following two links suggest. (actually they are slightly different in
calculation)

Is my method of obtaining the real etx values correct, and what will be the
possible cause of some overly large values among etx values measured.
And is there a way to change the dump interval of the routing table?
