I don't think it would be a good idea to continue. You're not supposed to take 10 days off in the middle of the program (I assume week 4 is actually week 2 of the base cycle). A slight adjustment of a day or two probably doesn't matter but 10 days certainly will. The purpose of this DUP program is to manipulate intensity and volume to promote supercompensation in a short period of time.
Within a given week the intensity increases while volume across sessions stay about the same. The following week the intensity drops at the beginning, making the work feel easier (but the volume increases) and the progression is repeated. Taking that much time off probably lead to deconditioning. I wouldn't take more than 2 days off between sessions (3 if absolutely unavoidable). If I couldn't stick to that frequency then I would do another program. Just let it go and remember next time not to take so much time off in the middle of the cycle.
Also, I'm not sure why you programmed based on 10lbs above your predicted max. Stick to your actual max. It's more important to complete the entire program and do all that volume work rather than struggle to get through, miss reps and train bad form.
Edit: Trying to repeat week 4 will be pointless. You might be disappointed by peaking for a rep max too because I doubt you gained much strength by partially completing the program and taking so much time off. I would suggest to restart the program with the old predicted max (don't go above that), doing the introductory cycle to get you back into shape for Smolov as you've done before. Forget about what happened in the last workout because you were deconditioned.
On a side note, whenever taking a long break (a week or longer) I always plan to complete a training cycle just before that break to recover. It could mean slightly compressing a training cycle to finish it in time. That way it has minimal impact on training.
