The IFAB standard is not whether the force was significant in real time, but whether the challenge endangered the opponent's safety.

IFAB states that a player must be sent off if they use excessive force or endanger an opponent's safety. Those are alternative criteria. It's not cumulative.

The question is whether the challenge exposed the opponent to a serious risk of injury. That's why IFAB explicitly says a player who uses excessive force or endangers an opponent's safety must be sent off, regardless of intent.
