Default Cam

Trying to understand full operation of camshafts better.

Say you have two of the same lift & duration cams, but the lobe ramp/degree is different on each. What is the effect to consider w/ how quickly the valve opens & closes?

I know it won't amount to much on my mild street motor; but I just want to understand the function... I just want to know... it's buggin' me.

So this is my cam-101 knowledge so far: (correct me if I am wrong)

How much it opens valves (lift)
How long it keeps valve open (dur)
When it makes valve open (lobe sep degree??)
How quickly it causes valve to open/close (ramp deg)
