Due to a bunch of people quitting I have inherited lots of dinos from huge Chinese/Russian tribes on genesis 2 and seen so many dinos with perfect stats(0 points in food, 0 points in speed etc) and they had insane stats. I also have a breeder tribemate that has traded for a bunch of top stat dinos and they all have stats like the picture you mentioned and a broken mutation counter. This is what happens if you spend months/years finding perfect dinos and breeding them.
None of what you state is correct. Here is a top stat Magmasaur that I was given and it has 7000 weight from points i put in it but crazy low oxygen as it was bred to not have pointless stats:
And the mutation window;
