Just my 2c on the program.
Pulling 10 on 5day for your first crack at 5/3/1 isn't too terribly under estimated. I would consider 8 to be the sweet spot, which tends to lead you towards 5 on the 3day and 3 on the 1day. If you only pull 5 on 5day, you are quite close to going to fail on 3day, and 5/3/1's general strategy is to not fail for long periods of time.
It is likely possible to do just fine with pulling 5 on 5day, but sleep and food needs upped a level to keep up, or general volume cut down. Like, a pure 5/3/1 program without assistance, but almost nobody does that due to addiction.
