1)The run/pass ratio slider at 100% means 100% pass, not 100% run. It's moved to the left (towards 0) to favor the run.
2)Some guy by the name of Hookemhorns over at NCAAStartegies figured out, with testing to back it up both in terms of played games and simmed games, that the run/pass ratio slider is tied to how the CPU uses its playbook rather than a straight up % of pass VS run plays. He then came up with numbers for the ratio slider that give fairly accurate results:

Basically what he found is that the % on the run/pass sliders is factored in the playcalling but so is the % of run and pass playsin the playbook. So setting it to 50% should not necessarily result in 50% passing and 50% running calls by the CPU.
