Not sure this is the right subforum for this topic, but it is kinda simulation related.
While commenting on cable cutters, I got to thinking about one of their advertised benefits: Less aero drag because of one body tube joint, not two or three. Has anybody quantified this? For most hobby rockets, I think the difference between one joint and two is negligible. Perhaps OR, RS, and RA software can be tricked to into modeling a body joint gap/discontinuity and generating a change in Cd, but I am not sure. Anybody tried it? Wind tunnel test? CFD?
