The day formula stored for this lot is Ascendant plus Jupiter minus the Lot of Spirit. Spirit by day is Ascendant plus Sun minus Moon, so the expansion gives Ascendant plus Jupiter minus Ascendant minus Sun plus Moon, and the Ascendant cancels. What remains is Jupiter plus Moon minus Sun.
By day the Lot of Victory has no Ascendant in it. Like Eros and Necessity, the two other lots in this set built on Fortune or Spirit with the Ascendant on the outside, it reduces to a purely planetary quantity.
Jupiter contributes almost nothing to its motion, moving about five minutes of arc a day. The Moon and Sun do the work: about 13 degrees 11 minutes forward and 59 minutes back, so the lot advances roughly twelve degrees a day, or one degree every one hour and fifty seven minutes. A birth time in error by two hours moves it about a degree.
There is a second consequence of Jupiter's slowness. Because the only slow term barely moves, two people born on the same day in different places and at different hours share very nearly the same Lot of Victory in a day chart. It is close to a generational point rather than a personal one, which is a fact about the formula rather than about the doctrine, and it is worth weighing before reading anything individual into it.
The reduction holds for day births only.
