You'll need to have an account with D&D Beyond, so you can view and download the test documents, and then, after a few weeks, they open up a detailed feedback form about the specific content they just tested. Each successive document won't necessarily reflect feedback taken from the previous, as they're doing along chain of many iterations which they expect to take a year or two - so for example, many changes the first document were then reverted for the second; this wasn't because of the overwhelming negative feedback (though consensus is there was), because the second document was already prepped for testing before they parsed the feedback from the first. They're testing things out and laying out feelers at the moment.
To Rag... I won't say you are the only one, but your view is not being sensible, so you're likely in a minority who are looking at it that way. No, Beatrice in this example would not one day be as strong as the gladiator, because she is not spending her life constantly working on improving and pushing her limits - she's not levelling up at any particular rate, if you want to think about it that way, while the career fighter most certainly is.
IF Beatrice closed her inn and took to a life of adventure in an effort to make the world a better place, and grew in levels and strength as part of that, pushed the limits of her potential to their extremes - then yes - she would eventually be able to attain the same maximum capability as the prize fighter, if said prize fighter also did so... because by the time they both reach those extreme upper limits of mortal potential, differences between race become inconsequential. IF you look at that and think it's 'silly', then yes, you're going to be in a minority.
