Port velocity average target fps?

chad speier is in that top 1% club of head porters/engine builders. His work speaks for itself. That being said, 1.67 torque per cube is astronomical, very few folks can reach those numbers.
I know that's out my league :), I'd be happy around/above 1.25 lbs-ft per cid just thought the limits are interesting.
David and Charles servedio both strive for 300 fps in a performance street strip engine.
That's where I was thinking the average build should be but just want to know for sure, hard to find much info on fps/velocity compared to cfm and csa.
