I tried looking in "Find", but did not see my question. The question is "Does a stiff suspension spring speed up a clocks Rate?".

Yes, stiffer spring means less swing and faster motion. You can thin a spring to increase swing. Of course the major speed control is the pendulum length.

Keep in mind that the length of the suspension spring also affects the timing of the clock.

I've always looked at it as a stiffer suspension spring has the same effect as shortening the pendulum rod. So, shorter rod, faster tick.

Yes, but as to how much difference it makes, it depends on the thickness and length of the spring vs the weight of the bob.

As an example, if you have a 14lb bob, and a 0.005" spring, making the spring 0.02" will make hardly any difference to the rate.
