That was the preference of the person who uploaded them on PSN. He combined my player movement sliders with his own set of sim sliders, which is totally fine. Alter them as you wish.
I was about to post in here about the major change in FG% even with sliders adjusted just by two points, its unreal the difference. I play with default HOF shooting, and in that video, I was shocked at how low I held the CPU in shooting (Which was promising, honestly, as when you play good defense you should be rewarded).
Other shooting sliders I like are 52 or 53 across the board for the CPU, and 47 or 48 for user. For those who are competitive with the game, but believe that 55 is to high for the CPU, and the gap of 10 points from CPU to user is too much, it's a great option.
We have to find a way to balance Sim, feel, and competition, which can sometimes be the toughest thing with sliders. Personally, it's a sport, it's basketball, so the competition aspect when I play the CPU is extremely important. I don't want to be running in for open layups all the time, blowing by defenders at will, and I certainly don't want to "fake sim".
If we can balance sim, feel and make it competitive, we have achieved a lot. So I am shooting for that with these sliders. Also, nothing wrong with using even all star as a base, its your user experience that matters, make it your own.
