just a little info but btf does not have "Categories" in their scoring. Yes they have a break down but that is just telling the judge's how much to factor each of those categories.
you dont actually get a score in techinique, performance, choreo and overall appearance. that is just what the judge's keep in mind. You get one score from each judge at the end.
Also regardless of if you think you are being kind, discussing kid's scores/placements its rude and not needed. Things could be totally different on a different day with a different set of judges! Its not this deep.
As a dance teacher I really struggle to keep my mouth shut on certain topics on here. I see it from both sides. It’s so hard to know the full story without being part of it…and even then people’s recounts of the same event will vary massively.
