Hi,

...just took the list on CC again :-)

Again - take a look at the IPSLA user guide - everything's explained in there. 
There are quite some issues to take care of when deploying IPSLA, e.g. 
one-way delay needs absolutely synchronized clocks. You can find more hints 
and background information in this document.

correct.

as stated above - one-way delay needs synchronization better than ntp...

For 2-way delay you could use RttMonLatestJitterOperRTTMax.
