The context: It's like there are two reactions and one has reacted for 6h while the other one has reacted for 20h. But there is no difference between them.
I want to say
There is no big difference between reacting after 6h and after 20h.
Is this example correct?
Or if could be more accurate to say
There is no big difference in the results between reacting after 6h and 20h
Or if there is a more accurate and natural way to form the sentence?
