Question on processor scrubbing

[Steve]

Hi,

I have a question on processor scrubbing. When a processor determines if a sponsor has approached the 1% chargeback threshold does it look at each individual site the sponsor has or does it total the charge backs for all the sponsor's sites? If the processor does incease scubbing due to a sponsor's chargebacks will it only increase the scrubbing on specific sites or all the sponsor's sites?
