It might depend how Friday's triple went and how hard this set actually was. I've missed the last two weeks set of 5 just because of shifting my weight and losing good leverage on my current weight. I'm repeating last week, but repeating this one is doubtful as I'm correcting my problem. Take all of that however you want.
If you're far into the program, advancing may not be the best choice in my opinion since you'll probably stall harder. If it was just some minor slip up, go on. If you really think you should repeat this week(for all lifts...why not for simplicity sake?) then do it. If you truly feel you can advance up that 2.5%, go for it and give it hell. Just be eating.
