I have to correct what I said here:
Re-reading Ben Dykes, this isn't exactly what he said. I'll quote him exactly to be sure it's clear:Profections were clear-cut, progress one sign each year by rotating the chart. But as Ben Dykes points out, by the Arabic era the progressed point used was the precise degree rather than sign.
Profections were used to read the affairs of houses. So what Ben is saying here is that each house of 30 degrees was counted from the ascendant degree, so that a house could have planets in two different signs. But Ben didn't say that degrees or houses were progressed or re-calculated, only that equal houses were used rather than whole sign houses. But I'm sure when we see the larger more complete book, there will be more details and examples on profections to clear up any confusion."For it seems that the older, Hellenistic approach to profections used whole sign houses. But by the Arabic period, astrologers such as Umar al-Tabari and Abu Ma'shar advocated equal houses: thus, instead of moving sign-to-sign, they moved in 30 degree increments."
