In Bedrock Edition, weapon enchantments and durability are not calculated based on the number of effective attacks that inflict damage on the opponent, but rather on the number of attacks. For example, when a weapon enchantment is knocked back, attacking a player with a higher fps (which can be reproduced with a connected device) will cause the knockback to stack, and the attacked player will be knocked far away, but the damage taken by the attacked team is normal, which is the effective attack damage in the attack (i.e., the invincibility frame prevents the damage from stacking), and the attacker's weapon durability is greatly reduced. Durability drop and knockback distance are not correctly calculated from the actual number of effective attacks taken by the attacker.(Using Microsoft Bing Translator, may not be very accurate ._.  ) (Seriously, it's really complicated for someone who isn't proficient in English to file a bug report      )
