Perspective:
Take the longer length and divide it by the shorter
e.g. 170/150 = 1.13
Multiply by 100
e.g. 1.13 x 100 = 113
Subtract 100
e.g. 113 - 100 = 13
That simple.
The answer is how much longer the longer cranks are as a percentage.
On a road bicycle, the gears are around 10-12% apart.
So with a step change of crank length, often the difference is no more
than about a change of gear on a bicycle.
Which means we are often talking about optimizing or fine tuning, not
major changes.

Last night another soldier, last night another child
No one seems to worry, no one sees his mother cry
They're just facts and figures on your TV screen
Another child and another soldier, is peace just a dream?
