Default Few Question about this Cam

I am thinking about using this cam. 228/230 585/585 112 +4 I don't understand what the 112 +4 actually means. I know the +4 means it has 4 deg of advance that is already set up by the cam pin so it gets installed that way. But what does it mean to drivability or set up. Doest it mean that it is like having a 116? If so then why not 116 w/ 0 deg at the pin? The higher or lower the LSA what does it mean for the end user? Sorry about all the basic questions
Thanks

The LSA is in reference to the centerlines and the advance is to bring the RPM operating range down a bit

I ran close to the same cam. xer lobed 228/230 .571/.573 lift with 1.75's so it was really .587/.589 lift on a 112

I loved it. sounded bad *** at idle and pulled like a crazy to 6500+
