Sometimes the rubber hits the road and you don't have time or money or any more cognitive energy to understand why your code that calculates a lot of things from a lot of data is not working in that 0.01% of cases
So you come up with a quick fix that's not exactly what it has to be done but it works it ships and it pays the bills.
Of course I don't advocate such solutions on critical paths, ate least not without some double checking.
