I've never done the sheldon thing yet, but understand what it tries to achieve. However, it may just be that there is a sligh high spot on on the chainring and on the spider, the trick may be to get these high spots 180 degrees opposite so they cancel each other out.
Therefore, try out all five rotational positions in turn to see which gives the best results, then when you've found the best do the sheldon thing with the stack bolts.
