I feel like this issue is the area where Campagnolo has the advantage over Shimano. with Shimano, you need to press and release the small lever 3 times to go 3 gears harder on the RD. this makes for at best, a clunky transition from big to small chain ring. Campagnolo allows a single sweep of one lever to change 3-5 gears in one press, making the simultaneous shift work very well. it was so easy to do naturally, I even taught my wife the fine art and she mastered it quickly!(I also don't like that fact that the shift lever is the brake lever for Shimano, but that is another issue.) I recently left Campagnolo for Shimano, but only for DI2, since EPS is WAY more $$ than I cold spare.
