Incorrect perfly depth complexity calculation

Has anybody already experienced that the average depth complexity
calculation used by perfly (Performer 2.0) is probably not correct?
We looked into the avg.d.c. in a real world database used for driving
simulation at different locations using a lot of dynamic models.
At some places the avg.d.c. seems to be calculated correctly.
But everytime you look at parts of the database where the local depth
complexity is (definetly) greater than 7 you get strange results. It looks
to me as if the local depth complexities are calculated modulo 8 (?!)
The result of this behaviour is that in most cases the calculated
avg.d.c. is of course too low. We seem to get an 'offset' of about 1 to
(worst case) 7.
Can anybody confirm this?
Has anybody any solutions how to get correct avg.d.c. values?
Thanks in advance.
