Question Ultimate Loss-IBNR

In some IBNR valuation, Actuaries derive their ultimate loss form combination of several reserving methods(chain Ladder, BF, Frequency-severity ). As example : Ultimate Loss= 20%ChainLadder + 50%BF + 30%F-S like this .
So, how we interpret this and what are the reasons for that???

The actuary is taking an average of different methods. The idea is similar to that of an ensemble model.

Like kind of credibility-average. You know, we can't give one method 100% credibility.

It's a convoluted way to gain consistency in an approach.
