The difference would be a single very large member compared to many small 
members. Each member consumes at least two kinds of space; some space is taken 
up by the member description itself, and other space is taken up by the data 
that the member holds.

Clearing the data from a large member can recover most of the data space 
although the member description space will remain. Clearing the data from many 
small members will also recover some space; but the ratio of space recovered to 
total space used will be smaller since there are so many more descriptions that 
still exist.

Further, with most physical files, the system has some obscure rules about how 
large a member's data space allocation will be after the member is cleared. 
(This might change in different releases, so might not apply the same on 
current releases.) I'm not at all clear on how this might relate to spool 
members, but it could complicate calculating how much space is recovered.

The purpose of RCLSPLSTG would be to remove the unused member descriptions that 
hang around after the members are cleared, and of course any allocated member 
data space for those members would be recovered as well.
