different color of shoes back I don't remember that's a that's good to check but like I like I guess like us as we have discussed like if Z is very powerful and potentially getting Co too much so I think I think there would be a balance there and this is kind of doing the cycle walk this is somewhat interesting some are similar to what we had discussed so maybe from A to B and then B to a a to be while I cycle through different noise sauce and then if you do this kind of random walk in an auto augmented cycle again
