The New Endland Firebreather Festival has released some basic standards for whether you should register as RX vs Scaled.
Weights for RX = you should be able to power clean for reps, in a WOD 155/105
Scaled = you should be able to power clean for reps, in a WOD 115/80
Skilled gymnastics movements might be present, but if you follow these guidelines, you will be in the correct category.
