Nele,
I didn't look at the size of your SD. When it is that large I totally agree
with Leonid, that CV is not a useful descriptor of variability. Note also
that whenever the typical value is close to 0 or 1, the distribution will be
very skewed.
Finally, a correction, it is the SD(P) that is approximately
OMEGA(ETA(4))*THETA(7)*(1-THETA(7)).
Best regards,
Mats
