Yea and you can go down two in back on shimano in one shift, and from what I read up two on some campy.....and that double shift might put you right where you want or need to be :-).
I'll admit I do not do it on the road much yet, but played around doing it some on resistance rollers this winter.......my sport-crafters rollers I need to get onto the big ring to hammer above 150-175 watts.....so I was working on that double shift :-). Most road stuff day to day the wind is so different I'm not proficient enough to read terrain and wind well enough to be 3 steps ahead on shifting like a better rider would be :-). Working on your spin is important too, being able to spin efficiently at 125 or more extends your range and might let you stay on one ring through some whoop de doo hills that might require shifting more if your spun out at 100.
The more you ride the more in tune with the bike you will get, but the chain sounds and feels different on the smaller cogs in the back...that plus speed showing on the electronics is what reminds me it is becoming big chain ring time :-). My Sora stuff has gear indicators but I never use them.
