HP41C/CV Time module accuracy factor

I have a question concerning the Accuracy Factor of a given time module.

Does it depend on the time module only (i.e. it's quartz) or also on the calculator (i.e. it's LC value)?

For example, if I have a accuracy factor for a given time module in one of my HP41*, can I use the same accuracy factor if I move the module to another calculator? Or do I have to recalculate?

The AF is specific to the crystal oscillator in the Time Module itself, so it should stay fairly constant across machines. The condition of the batteries will probably have some effect, but that's all.
