So using #1 axle connectors as the linkage, we get a reduced piston expansion,
down to 86% of maximum.
Using technic axle joiner perpendicular, we can reduce the range to 70% of
maximum. I can't think of a way to make this any smaller.
Reducing the expansion range of the piston also reduces the leverage the piston
has on the switch, making it harder to throw, increasing pressure requirements.
Ignoring the pressure issue, a simple reduction of 30% of throw, decreases time
by 30%, so the increase in step rate is less than doubled.
