Another cam degree question!!

The last time I degreed my slant engine I did it a few times.
I have my method, for whatever reason and plot the events every 10 degrees in excel.
Now during this latest work I found that my timing set could not be installed "dot to dot"
It's a double roller set I purchased from the Cox Brothers a few years ago.
I think it might be from down under, no markings.
But painting dots on the center of the cam bolt and the crank bolt,
and highlighting the dots on the big and little gear,
it would NOT line up.
So it has to go in either one tooth retarded or one tooth advanced.
It is close, bot not dot to dot.
No big deal since I have offset bushings and I get pretty close to what I need or wanted.
I really guess on a street engine the misalignment forward or aft would never be felt.
Anyway just more wood on the fire.
