Every cam I've degreed in recent years was 4° advanced when installed "on the pin". I've always assumed this was to compensate for chain stretch.

ok, how do I check it with the open/close specs on the card?
Google "how to degree a camshaft" and take your pick...

For the life of me i can't understand the reasoning for the cam manufactuers doing this. Just make it straight up. For a stock engine, dot to dot. Race cam degree it in like it should be. Maybe cam guys did this for the person who has no idea how to degree a cam in the first place but knows how to dot to dot. Reminds me of the time a dude brought me a 383 that wouldn't fall out a tree. Checked the cam and found a 8• retarded button on the cam pin and 4• retarded crank keyway. After i fixed it i told him not to touch the engine again, he said why...
Problem is dot 2 dot isn`t always where it should be.........
For a 318 2barrel it is or any dead stock engine for that matter

Any time you introduce aftermarket parts into the mix, you run the risk of parts not being machined or stamped correctly.
I always degree a cam even if its a stock rebuild!
Dot to dot does not cut it!
