One of the few changes I make when using Charter's sliders is that I Up CPU pass block to 45 (he uses 35).
My biggest reason for this is that when I play Madden I exclusively control my LE and DT's, and occasionally OLB's or MLB's. But for the most part I control the LE.
That means I tend to do far too well against the run and with getting sacks. So I have always given the CPU 10+ from what Charter says for CPU pass block and run block. (I have been using his sliders for years but I always give more CPU blocking)
So I use Charters sliders with CPU pass block at 45 and CPU run block at 65.
If you often control guys on your D line like me... you should consider doing the same. I only get like 2-3 sacks on average. Sometimes 4+ of I'm up against a bad O-Line.
