Tuned Futility Equation @Vizvezdenec array suggested that alternate values may be better than current master (see pull request #2270 ). I tuned some linear equations to more closely represent his values and it passed. These futility values seem quite sensitive, so perhaps additional Elo improvements can be found here.
