Great buck.Congrats!
Not trying to take anything away from you buck, But I highly doubt 154.
I think they added a spread measurment that wasn't supposed to be added. A 150's eight point is a massive a 8.
Read this site and try it yourself. Just make the measurments and enter them. No figuring needed.
