Camshafts, idle quality, driveability and LSA-REAL WORLD EXP and OPINION

and here i thought you started this thread to watch the feathers fly,lol! i have a tough time ingesting the ''math'' of it all, my mind shuts down just like it did in high school, i failed math! i have a handle on lift and duration at 050, after that my brain pushes back, ive read this and many other threads(arguments) on cam timing and i decided awhile ago i will just follow the old direct connection formulas for performance, just my take on it!
