Too much timing?

I don't understand why you guys insist on running so much timming on your mild motors. There is absolutely no reason to run 20degs initial on a mild small block, especially when your total is way off the scale.. Most mild SB's run just fine around 12-34. If you are at a track, ok try some different settings. But for an every day driver/street car, there is no reason to ring the car out on the jagged edge over timming it. 12-14/34-36 will be more than sufficient.
Im just trying different stuff. I have read different ways to improve performance with timing and tuning and im just trying it out. Im new to this part of it. Im just trying to learn. I agree it does sound extreme I thought it was alot of timing too that what made me want to ask questions. Im gonna have to limit my dissy either way. I originally set it around 14 and it runs good there.
