I found this on the M5 Board back when I had one. Applies to SMG or M-DCT

"Without being on the accelerator the downshift throttle blip will assume you are still decelerating and rightly be short of the perfect rev match. It blips up enough to protect the transmission and clutch and to prevent an engine-load jolt, but not so much that it slows the engine load. When you do your final gear downshift in anticipation of entering and accelerating through/out of the corner, you should be giving some gas when braking and downshifting (heel-toe or left-right foot brake-gas). This signals the SMG to rev match higher and when it completes the shift, it will start loading the suspension through the turn-in for better balance and a smoother/faster braking/acceleration transition."
