i don't really understand why E8 and LSI are so incompatible? (i mean, E8 and a logical type with Se, that is just totally NOT POSSIBLE! in other words, what?)

since no one need actually reference anything or define anything or state anything other than x variable vs. y variable vs. z variable in x system vs. y system vs. z system vs. whatever, then i don't need to either. i can just use these terms as they are and assume we all mean the same thing (when i'm sure we don't).
