CNS impact of 250-300m

Ya 4 Hi sessions per week. But every Hi session is not created equally. I just get the sense that the lactic type 250’s and 300’s dont drain out the CNS nearly as close to 120-150m speed endurance does and thus can be incorporated more frequently without having too much additional CNS stress.

So, you are thinking of adding a SE session and you expect more or less the same CNS stress? And although important, is this the only factor you are concerned with? You can try it and let us know how the season goes! As I said, IF for some reason I had to try this, I would definitely go with a 2-1 format. We all live to learn though!
