Yes I think Danny D is about the same size as Lex Steele.
So their Dildos are bone pressed length?
Yes. They would also take before and after bone pressed measurements to be sure that the dildo was accurate to the guy's biggest possible size. When the mold is put on it must be right up against the pelvic bone. to close the gap.
There is no way they would make those dildos shorter than the guy actually measures if anything they would make them bigger. The 2 inches extra is usually the standard, hence why Danny D's measures 8.5 Lex Steele's measures 8. Prince Yahshua's measures 8.1 (but he has a curve), so they are measuring from the bottom to the top of the bone pressed length on his, which is actually accurate for an upward curve specifically.
