For the first time, I've been brought in as a new reviewer on a manuscript that received an R&R. Previously, the paper received (and responded to) 3 very thorough reviews.

Do you do anything different when you've been in this position? If so, what do you do? If not, why not?

Thanks, everyone! Very helpful.

I decided to use the Blais Heuristic (from @ablais_udem). https://twitter.com/ablais_udem/status/1245827247552040962
