Maybe I'm missing something. But don't we assume at some point (e.g. gas change events) that we can refer to cylinders via their content (i.e. O2/He permilles)?

To me that suggests that we could proceed as follows: We maintain a per dive list of cylinders referenced by their content (maybe using our gas sorting rules). Upon a merge in question we do a set union (i.e. count each gas only once). And we chage the code such that when we refer to a cylinder we either do that by iterating over the list or by content but never explicitly by index (here the perl programmer is speaking: There I would implement it as a hash with the content as key).

The real probelm is:

subsurface helling$ cat *c|grep -c cylinder
411
