Decreasing/Increasing in calculation（運行資料減少／增加）即是一例，系指當行星在黃道上真實的運行/位置（true motion/position）比其平均位置更靠前時，就必須將其平均運行/位置（mean motion/position）的資料加上偏差值（equation），即運行資料增加。而當減去偏差值時，即運行資料的減少。
而運行數字增加/減少（Increasing/decreasing in number）系指行星每日運行的速度（或至少是指行星的本輪[epicycle]中心的運行速度）看起來是加快（或減慢）的。當行星從近地點（perigee）向遠地點（apogee）前進時，由於離開地球愈來愈遠，其運行速度看起來是減慢的；若行星從遠地點向近地點前進，則因距離地球愈來愈近，其運行速度看起來是加快的。
And look too at the Moon: for if you found the Moon in a good place (along with I stated of the suitability of the second place), and looking at the second place, increasing in her calculation and her glow, trining the Sun, and Mars not looking at her, it indicates that he will be known, powerful in leadership and action in the cities and the work of kings, trusted among them, influential for that reason. But if what I stated was just as I stated, and the Moon decreasing, then it will reduce him and they will not present his management favorably, and they will not have praise for it.
In this, let the Moon be in some feminine angle, also the lord of the Ascendant, subtracting in motion. But the lord of the Midheaven and Mercury should be safe. And if the Moon were with Mercury, it will be useful. If Mercury were even in his own lesser course, it will be good. ‘Umar al-Tabarī said, the crooked signs are good for those buying, and even seem to help sellers. And if the Moon were in signs ascending in declination, increasing her number, it makes whatever someone then buys, dear—and contrariwise.
