If I put my gauge on your engine and used my technique I would get different numbers from yours, so don't be concerned if other responses claim higher pressures. Most of us amateur mechanics have cheap gauges of questionable accuracy, but they usually get the important job done - detecting differences between cylinders.

As you noted, the important thing is that the pressures are very close, which indicates that everything is sealing up well, and the engine is in great shape. Sounds like you did a fine job.
