thanks! klods hans confirmed yesterday that the revised probability is independent from the league. If this is correct, the loot probability in fighting Platinum, that is provided by the source (48%=1732/3611), is the answer on my question ( loot in fighting Diamond).
Apologies for being so tedious. From my understanding this one is one of the most important parameters as GbG Diamond league is the most relevant way to harvest the massive Investment in fighting GBs. kind regards, Jue
