(meteorobs) meteoroid orbit vs parent body (comet)

[chiayk]

Hi folks:

          How accurate is the 2-station meteor orbit obtained from say 
one single meteor from two adequately spaced stations  videoccd setup in 
terms of the calculated meteoriod  6 parameters vs Parent Comet.  ie  
Arg of Perihelion /Ascending note/ Inclination/Perihelion distance/ e/ 
a. Do we expect close matching to the parent body (comet) ?
 Is there any example - tabulated numeric examples to show these. 

         Thanks
