Unmodified KERNAL initializes TED in double clock mode. You don't have to do anything. Turning off double clock mode will slow down the machine.
Keep $FF13 bit 1 zero. Don't touch $FF07 bit 5 ever, keep it zero. If you need more speed turn off screen with setting bit 4 in $FF06 to zero.
YAPE is accurate enough. If you don't see what you expect you either have the wrong idea or your program needs debugging.
