A blade alignment deviation of 1/64" across the span of the blade is quite a bit....especially in the direction it's going. It's likely to cause binding, which could lead to kickback....a very precarious situation for a newby or a seasoned veteran. A little deviation in the opposite direction would be less hazardous, but I'd encourage you to get this adjustment within +/- 0.003". If you can't adjust the blade to where it should be, at the very least, adjust the fence so that it's parallel to the blade...it's not ideal, but it's the lesser of two evils.
It's odd that Delta would put a full kerf splitter on a 13 amp saw....it's a perfect candidate for a good 3/32" thin kerf blade, which is easier to spin than a 1/8" full kerf blade. Plus, I'm not even sure that the retailer of this saw (Lowes), even carries a full kerf blade.
