• The original statement Dror made here was '$W_{J}$ of any chord diagram is, you EITHER replace a chord with a bridge OR you replace it with $-2$ times a nothing'

I think he actually meant '$W_{J}$ of any chord diagram $=W_{J}$ of the diagram with a chord replaced with a bridge $-2\times W_{J}$ of the diagram with the same chord removed'

DROR: PLEASE CHECK THIS AND CORRECT ME IF MY GUESS WAS WRONG.
