I took over tasks in the area A for the market for which I am working. There are about 20+ markets in total. It's possible to objectively access how good you perform tasks in the area. There's one KPI that's always used.
We had a meeting to assess how well markets did this month with the task.
Although I did it for the first time, my result in terms of the KPI was twice, trice as good as the result of most other markets. My result was a clear (positive) outlier. The participants told me they were totally impressed.
And then... I told them I had an easier task than other markets because (input an objective reason here). One of the participants confirmed that if the reason was correct, my task was much easier then. The thing is, I thought about it and the reason doesn't seem to hold. The complexity seems similar for everybody.
Is there a way for me to point to that? Should I just attend the meetings in the future and in case the situation repeats tell them "Hey! My task doesn't seem easier after all"? How to do that in order not to sound boastful?
