Cylinder Balance: The cylinder balance test calculates % of efficiency using current RPM. RPM is gauged with all injectors running normally. Injectors are then cut 1 cylinder at a time and the new RPM is compared to the pre-test RPM to determine % of efficiency.

you can't tell how "good" the seal is, compression/leakdown tests would be much better for this, but you can certainly find out which cylinder could potentially be problematic

Yes, run it a few times and youll see just how inacccurate this test is. Its good for diagnosing a problematic cylinder, but not so much for telling the health of your motor...
