Buying Groups/Buying Circles and impact on Lead Scoring

We are in the process of starting to cater for buying groups/circles in our CRM instance. This refers to the fact that a majority of our clients don't only have a single decision maker in the buying process, there are normally a group of people making the purchasing decision.

I realize that this will predominantly be a function that is catered for in the CRM platform as it relates to attribution, but I was wondering if anyone else, who has successfully implemented buying groups, would be able to share the impact on their lead scoring model, if any?

Thanks,
