really helpful video! got a question tho is there a clear difference between the "normal" shapley value and the shapley-shubik index? i dont seem to see understand where they are different :/ if i was to calculate the "normal" shapley value for your example at 11:30 i would also get the exact same result, the pivotal player in the normal shapley value would just have the value of 1 in the marginal vector which would result in the same thing at the end for me i need to know if i got one of the two wrong :/
