I have been trying to explain to a project how response time contribution is calculated in a Service Flow diagram. I have been referring to this answer but came across an inconsistency in the calculation results for more complex service flows. Can someone please tell me how response time contributions are calculated and why my calculations seem to be off in Example #2 attached?

The formulas I'm
Note: The first formula I got from this answer: https://community.dynatrace.com/t5/Dashboarding/How-is-the-response-time-contribution-in-service-flo...
Thanks for the reply Sebastian. So please correct me if I'm misinterpreting your answer. But from that I'm getting this formula:
(Average Time on C) = (Average Time on Root) x (Response time Contrib on A) x (Response time Contrib on B) x (Response time Contrib on C)
which becomes this formula (when trying to get the contribution time on C):
(Response time Contrib on C) = (Average Time on C)/( (Average Time on Root) x (Response time Contrib on B) x (Response time Contrib on A) )
When I try to apply this new formula to the two examples in my note however, the results still do not match the response time contributions reported on the Dynatrace Servce Flow. Are there any other factors I'm missing here?
