Add compensation factor to adjust extra time according to time control As stockfish nets and search evolve, the existing time control appears to give too little time at STC, roughly correct at LTC, and too little at VLTC+. This change adds an adjustment to the optExtra calculation. This adjustment is easy to retune and refine, so it should be easier to keep up-to-date than the more complex calculations used for optConstant and optScale.
