it is good if somebody can judge about his experience and therefore the
quality of his own observations. However, don't make yourself worse than
you are!
In 1995 I plotted the Lyrids together with another observer. That was the
first plotting session for nearly five years, so we could really be judged
as beginners at this time. Later I analyzed the plots and compared them
with the meteors MOVIE had recorded in parallel. Even though the error was
sometimes quite big for single meteors, the overall error for backward
prolongations to the radiant was astonishing small! I used the Radiant
software of Rainer for both visual plots and video meteors. Even though
the video plot looked much more focused at the radiant, the resulting
radiant position of those ~30 visual plots differed by only one
degree from the video meter radiant!
That is, even with less accurate plottings you can obtain good radiant
positions! However, you need more than a handfull of shower meteors to get
good statistics.
