so i’m studying the jumper tables - usef. But noticing that some people refer to the different rules as Table a, b, c while usef only uses Table 2 through 4. (no Table A’s or B’s etc)
And one document i’m reading says “table A” and parenthetically (usef : Table II, section 2 ).
So what organization uses …or where did the Table A, B, C come from?
