I agree and it's like we don't even need because we have so much data I don't even think we need to do use that assumption anymore we can really say valid like what is what is the range where you get this maximal risk reduction we have that and And we can just say okay for the guidelines like let's use that 5 to 35% risk reduction and say for 5% risk reduction you need x am minutes and then up to 35 you need that that's where the dose response is and that's how much activity you need.
