I think this makes sense to make the limitation on the product, since IMO if you need a period longer than 4 seconds then the runtime is much shorter due to that you want to express something like executing for 100ms each 10s. Much less likely that an application would need to execute for 7.8 s out of a period of 8s and would not be happy with 3.9s out of 4s.
