How to address gap in performance on my resume?

Hey War Room! One of my first posts here. I'm getting ready to look for a new AE gig and I'm seeking your advice. I've been in tech sales for 6 years. Most recently an Enterprise rep selling in SF for the last 3 years.

I've been fortunate to have a track record of performance where I exceeded quota for the first 4.5 out of 6 selling years, with several trips to President's Club.

However, the last year and a half, I really struggled. Only 2 reps within my global enterprise organization actually hit their annual numbers. I achieved 80% to quota and was #5 of 40 within the organization.

How should I address this reent performance gap on my resume? I'm hesitant to drop 80% to quota on there... but I also want to be honest and speak to the fact that I was still in the upper echelon of quota attainment (relative to the organization). Give me your thoughts, I'm open!
