The revised BV for UR quad encourages cheated quads. That would be unfair to skaters who have better technique. Maybe the tech panel would be more strict with quad rotation when they review the jumps, otherwise we may see more cheated quads getting too much reward.
I don't get the logic for raising the bv of easier triples. The only explanation I can come up with is that they raised the bv of easier triples like 3t and 3s to compensate the difficulty of combination jumps because these two jumps are usually used in combo rather than solo jumps.
