I highly recommend a leak-down test to determine the problem with cylinder #3. This will pinpoint the source of your leakage. A shop can do this for you quickly.
As mentioned, the wet-test compression result for cylinder #3 should most definitely be higher than the dry-test result for the other cylinders. The wet-test result should essentially compensate for ring problems and it hasn't completely done that.
You cylinder-to-cylinder dry-test results are worth being concerned about.
