Come on, this kind of "made up rules" is meant to be ignored, not followed. Normal players would have dropped and ignored that extra stat digit, either because they recognized it as a plausible deniability tool whose usefulness is limited to written material or because preferring D&D-like stats is an obvious corrective "house rule".

Yeah, that rule was clearly just there for show. Just like the second digit on levels ("number of professions you've mastered").

There were some rather elaborate rules for constructing armor that didn't really map to D&D's armor class, though. Probably even more of a curve ball.

The hit points – sorry "hits to kill", my mistake – were either what you'd expect from a D&D character with the same (first digit) level or the sum of (the first two digits) of Constitution and Strength.

Don't remember much more than this…

I think this is an easy conclusion to reach in this context of a licensing discussion but no player is going to, in the usual context, open a book they've never heard of and think all of the ridiculous rules were put there to avoid copyright issues.
