The table keeps a history stack I think the default is 30, you can change that however.
But your previous revisions will sit in the database until they drop off the history stack
Do you know what initiates the drop off for the history stack? Is it a re-save of the collection item?
I have defined the Buffer to 10 and didn't see a reduction in the table size for perch2_collection_index when resaving items - only an increae.
