Low impact, since the chances of passing a valuse above type(int256).max is relatively slim.
Take a look at calculateScore():
Do note that the function is used to calculate a membership score given some amount of xvs and capital, issue is that both alpha numerators and denoimantors are passed in as uint256 values and then while getting the exponentiation value these values are converted to int256 which would cause a revert.
Better code structure could be applied, from the get go the values passed in for numerators and denominators could be checked to ensure that they are not above the max value of int256.
