how long does it take for torches, hammers and frogspawn to split?

I've looked this up several times with no definitive answers.
Obviously everyones tank is different, with different equipment, water parameters and color morphs, but it would be interesting to see what peoples timelines for euphyllia coral spliting is.
My torch coral has had a second mouth since right before thanksgiving and is still in the process of splitting into two heads.

What are your experiences with how long it takes for a euphyllia coral to finish splitting into two clearly defined heads?

Too many things to factor even actual species, example my electric green grow fast split fast too but my green ones grow half the speed literally and they are on the same place on my tank. When I get 4 heads on my electric my green is barely into 2 heads

Yep I have a frog that has about 30 heads and has sort of stopped growing new heads. I have another that has grown 4 new heads in 6 months.
