Scaling of the panel provided

Dabura is accelerating towards the light which his CT launches with the mass behind it like we saw the light appearing on maho then the attack comes .

" More more __ keep going reach the light " - this statement shows acceleration

So it's not instant but acceleration

He takes some time to reach his top speed because if he had reached his top speed and collided with the buildings then the KE explosion would have happened .
