I wonder how you deal with Score Decay: What is the average time frame and what factors do play a role here?

Hello everyone,

I wonder how you deal with Score Decay. Score Decay refer to the situation when your lead hasn’t been active within a certain time frame (Let's assume 3weeks) and you deduct from their score for the lack of engagement. My question is: What is the average time frame to deduct score from a lead and what factors do play a role here?

Thanks!
