His program works so I see no point in messing with it, when Some can match a 550kg you tend to listen to them.
As for assistance, if I do any I give them a reason. I don't just do them to fill an hour
Just thought I'd post this up mate, from a well respected lifter in the States that is strong as hell and has been using 5/3/1 on and off for a number of years:
"I think it's good you're looking to modify 5/3/1. Templates are good for a starting point but when you individualize something it will suit that person even better. Cookie cutters only work for so long. Like take my program, it's different than 5/3/1 b/c my program focuses on the assisting lifts and not the staple lifts (which is the opposite of 5/3/1). There are also other differences like my assisting lifts changing every 8 weeks. What I'm saying is I took ideas from many programs and my own ideas and put them together. I think that is the way to build the best program for yourself. You know your strengths and weaknesses better than anyone so you can create the best program for you. Just use a solid foundation to build upon it
I thought that was a great post with good logic applied. I personally don't think it's a bad thing to change or tweak the programme to suit someone, but saying that I would be thinking more of someone that has a good amount of lifting experience behind them. If it's someone that's more of a beginner then sure, leave it as it is because it works well and it's design layout is pretty much fool-proof.
Just my 2c
