"Activity level of a planet" in a yoga

[Haumea]

Hi everyone!

I've been into Vedic Astrology for many years, but have only recently started exploring some of the yogas in my chart beyond rajayoga.

Apparently I have a Malavya Yoga in my chart (Venus in Libra in 4th), but according to one website (https://www.astrologerpanditji.com/page942.htm) I've been reading it only makes a big difference if the "activity level of the planet" is high, especially above 80%.

Would anyone please explain how the "activity level of a planet" is calculated, and whether SolarFire has such a function (or is there an online calculator?)

OK, I think that probably translates to shadbala.

Venus is the strongest planet in my chart (#1 rank.) I don't know what it is in %, but it has to be up there.
