Vito , I believe that every 4th or 5th leaf should have some signs of varigation, if it doesn't then you should remove them and hope for the best. I think once it goes completely to all solid green leaves then it'll stay that way. I recently did an airlayer on one of my tigers and had one shoot come out all green compared to the main shoot that is highly variegated and I just removed the whole green branch. It may be too late for yours., I think that's why they were advertised very clearly that those jolly tigers on ebay were NON variegated.
