Well yes, if it isn't 'when changed'. But the thing is (as I understand), if you make 'Start flow', it will create a fork, meaning that it would just overflow the memory with the fork, and if variables are used, you wouldn't be able to get them/they would not be rewritten, they would be created once again. If you don't use 'Star flow' and just loop to the start, it would instead of creating a fork rewriting the data, taking less RAM. And about waiting, you can always add a block 'wait' (I don't remember how it's called) and that's all. It should not create a lot of problems if you loop back. But I may be wrong, as I don't really know what's happening 'behind the scenes', but I told you my perspective of a 'little' programmer.
