In Step One we used the numbers in the He Tu to produce columns of three tiers each, which we used to calculate a score for each of the eight gua.
We now need to produce a further set of columns using the same formula (i.e. the middle tier is equal to twice the base or lowest tier, and the uppermost tier is three times the base) for all bases up to 90.
Of course, the bases still alternate in character between yang and yin, and we use the same idea of pairing that we used in Step One (e.g. where we paired one and six, we now pair eleven and sixteen, twenty-one and twenty-six, thirty-one and thirty-six, etc, etc).
To use the example of Zhen again.
The score, now, of this gua is 31 + 72 + 108 = 211.
Each of the eight gua needs to be calculated for each He Tu pair in each row of columns. (Again, though, we do not use the He Tu pair corresponding to five and ten - e.g. fifteen and twenty, twenty-five and thirty, etc, etc.)
For simplicity's sake these scores are not presented on this page but on the next, which is our penultimate stop, and which displays the full set of four tables (plus the central one derived from them) for each of the nine rows of columns.
