This is a pretty silly thread.
That's why you should bring a cheat sheet, or write some numbers on your hand like you did for a high school test. This way you just have to find the right numbers to choose the correct gear, Hopefully before you crash into the trees.
But seriously, with my triple chainring I just pick the one that I anticipate I might need soon if its important, Like climbing or for quick acceleration.
This works best if the cassette cogs are spaced correctly. For me, that's a 10- 13% increase with each up tick
My 1'st derailleur bike was a 10 speed racer with a 2 x 5 speed drivetrain. Because the 5 rear cogs were spaced widely apart, The engineer who designed the bike chose to use chainrings that would put a step between each rear cog. So while the single shift was a bit higher then ideal, If it bothered me, I could always find the next gear up or down. With just 2 chainring's it's easy to do.
