Typically how long does a leak down test take?

My experience is that compression tests can be all over the lot. I think the important thing is that you do it a few times under the same conditions in a consistent fashion.

Something even as silly as a weak battery can give you low readings.

Or a bad negative terminal that got corroded over the years. change it to a new one if that's the case.

When using cheap gauges, it is much more important that the compression is even across the board. I've seen some gauges read hilariously low (like 130 when they were supposed to read 180 on a quality gauge).

Default Low compression

I also have low compression in all 4 cylinders but my numbers are way worse. 1-60, 2-55, 3-60, 4-65. I did each cylinder twice when I did the compression test. The car has lost a noticeable amount of power (obviously) but it still runs fine. Anyone have any ideas on what could cause such low compression??

I'm surprised the engine would even run if that was the actual compression. You could have lower then optimum compression, but I suspect you have a bad reading gauge as well. Id try a different gauge and see how it compares first.
