I'm trying to figure out why (if) this line works to test the 95th percentile. Could we simplify this and just use pre-determined values: e.g. define two arrays `samplesToSend := []int { 2, 5, 1, 9, 12, 8, 19 }` and `percentileToExpect := []int{ 2, 5, ... }; ` and then send the first array to the sampler, and expect the outputted samples should have the expected percentiles in order?
