There is a people are so focused on e data part ins kin of fine tuning things thee and looking in all the details, that they completely forget about the bigger picture. So for customers, that's why i really laugh a lot of your pot casst because actually the same is very, very much true with lots of statistics and data science. And then you optimising on stuff where everybody's like, what are you doing? I'm optimising this year. But we made the decision two weeks ago. What did you do since that optimizingis?
