Why ghum taking leap when it is getting same trp as anupama

May I know why they are doing it with ghum. Despite copy paste of popular show & no support from previous slot, it is still getting good trp. It is in top 5. It's not like the difference between other shows is any high. Except uka, other top shows are just 0.1 higher than ghum. Then why only ghum taking generation leap.
