Variegation is a complicated subject. Variegation only occurs within clusters of cells. Those that lack the gene for the production of chlorophyll. They will only multiply in certain areas. If the area that has the mutated cells is part of the new shoot, then it will be variegated to some degree. This is the simplest answer that I can offer on this subject.
Now, the only thing that you can do, is continue to kill off the green only shoots, leaving at least one new shoot regardless of variegation to gather energy at all times, until you get a variegated shoot. Then it will be likely that the leaf will produce new offshoots in the future that will be variegated.
Thx for this answer.
I'll seprate green shoots hoping new ones will be variegated.
