my guess is that it's less that 1 degree,less that 1 minute kinda thing.

40 seconds of a degree

360 Degrees to a full circle
60 minutes to one degree
60 seconds to one minute
40 seconds = (40/60)minutes =(40/60)x(1/60)degree = 0.01degree
By the way a minute of TIME in the last machine shop I worked at would cost you $2.

Yes, that is correct.
Tony, I have a very nice rotary table if you need to use it. It is already mounted to the Mill, I was using it today for these blocks.
