What is lifting heavy?
All these adjectives are so subjective that they're almost pointless to discuss. I don't keep logs around to pore over at a later date, in fact I delete my app data frequently because that shyt doesn't matter. Simple things like life stress and work tempo, food intake, motivation, sleep, etc. all affect output so much that worrying about or over-analyzing that shyt.
I know I was totaling over 1400 raw with wraps less than two and a half years after I started, and have strived to produce at least one PR each year. By doing that, I usually end up bigger and stronger on more than one lift incidentally.
Six days a week is also pretty arbitrary. If the program calls for 6 days, I do six. If it calls for 4 or 5, I do that. If it calls for 7, I do that. If I happen to have extra chakra and a time-specific goal, I might be doing two-a-days. Is your six days better than your 4 or 5? Can you recover from six heavy days? Can you afford the extra time? Not sure why that metric even matters tbh.
Name dropping those programs doesn't do much if you can't reproduce the same conditions under which I run/ran them. I've been modifying programs probably since month 5 or 6, so invoking a vanilla program versus my specific modifications won't do anyone too much good.
Not sure why this seems so unusual or interesting to you, I simply do what I need to do to accomplish whatever goal I have. If it works, cool. I'll absorb what was useful and reject what was not. If it doesn't, I'll assess where my shortfalls were and re-attack.
I also flow with whatever constraints I have at the time. If I have to change jobs and stay on the move, I'll shorten up the WoDs. If my job isn't pushing me like that, I'll bust out the longer workouts and double-up on days. If my schedule has me moving to where I can't cook, I'll eat out more to increase the macros. Be like water, my (non-friend) friend.
Answering these questions isn't value-added for me so I'll be moving on after this post.
