Whether I use Tim's method, or use a timing light, I don't call it good enough until I drive it under load to listen for the telltale light ping. This can be done up a hill in 3rd gear when 2nd gear would have been a better choice. I then advance it a degree at a time from there until the ping is gone. If you get greedy and advance it too much past the ping position, you will loose power.
