Cactuar, you should edit this. Currently the DSR and DSRM are backwards. For myself personally, that is why I had them mixed up, but when Sheridan explained it on the MIOM stream, they were opposite to this:
The way it is currently is how it was in the previous ruleset and every ruleset before it afaik, as I just copy and pasted that particular piece. "I thought they were the other way around" is not an excuse when definitions are provided within the ruleset regarding what each means. Dave himself saying that it is one way or the other is not important, as the nature of language and definition is democratic, and the reviewing group for the ruleset, which was the entire MBR at the time including Sheridan and you, all agreed to this (or glanced at it instead of reading it thoroughly, because everyone in the MBR did essentially nothing).
I'd rather just remove the titles of DSR and DSRM and insert a line like:
Stage Elimination: Stages may one be used once per set.
or
Stage Elimination: Players may not counterpick to any stage that they have previously won on.
or
Stage Elimination: Players may not counterpick to any stage they have previously counterpicked to.
Associating the titles of DSR/DSRM with an assumed meaning has created problems. I'm really tired of people trying to put a name on these rules because they want some kind of credit. It instantly makes it feel less professional/polished.
