I compiled all the spdats I've found into a spreadsheet that shows changes over time.

It looks like this was a Root for awhile, then was broken for awhile, then had a 95% snare as of August 2001, the last date I have a spdat for.
There were other changes too to the slow % and to the number of counters.
