Well 20" high would make it:
20 x 4 = 80", 80"/12 = approximately 8' 4" in full size
. That is definitely not 1/4 scale, way bigger, somewhere between 1/4 scale and 1/3 scale.
Assuming Sue is about 5"7, that is 67". Divide by 4 gives 16.75" for the comiquette IF it was 1/4 scale.
Website lists the statue, including base, at approximately 16"high. If base is 1", than the body length is about 15".
Working calculations again, this means that at 1/5 scale, she would be 6'3". And I am pretty sure she is not supposed to be that tall.
So if the specs are right, this piece sits somewhere between 1/5 scale and 1/4 scale.
I am not sure what SS is doing here with the scale, assuming the specs posted, and the arithmetic is correct here.
Personally, I like the FF, and I like the sculpt.
