I got these 3 quotes that talk about the benefit of deloading from a forum called "weaker after deload weeks?".
Mark Schoenhard said:Not being a gymnast and practicing gymnastic strength I fully trust the program. I feel one needs to be practicing this program several years before fully understanding deload. Deloading helps the body restore and recover to prevent injury and promote gains. Being injured is being weak. Be careful.
dynamo said:If you haven't been doing these exercises for very long or with high enough intensity there's a good chance you have not neurologically adapted to the movements. To keep the neurological patterns developing you s/ grease the groove modestly in between workout sessions and even during your de-load week. Don't over do it, just enough to keep learning the exercise, so maybe short static holds / low reps, depending on the exercise, once or a few times a day. Remember you don't want to cut into your strength when it's time to gb it.

Also, on a scale of 1-10 how intense would you say your Deload weeks are? It could also be that you in fact aren't fully recovering during your deload week and thus when you attempt the next week's set/rep template your body has not yet had the time/rest it needs to supercompensate, especially if you are really pushing it and working close to your max capacity fairly regularly.
Maybe try significantly decreasing the intensity of your deload weeks to the point where they just feel like "practice" and not "work", or even reducing the intensity of your 1st and 2nd weeks of your microcycle (if you are working close to max capacity on those as well as your 3rd week). Also pay attention to your nutrition, rest, and recovery modalities as a weakness there could be inhibiting your body's ability to adapt.
Hope this helps and you can figure this out.
