Sometimes it takes 2 needle adjustments and sometimes even more. My machine has a 1/4 inch setting for using my normal foot but still have to narrow it a couple of notchs.
I use Eleanor Burns method for perfect HST and no distortion.
I'm glad you said that about the block taking a smaller scant seam when the block has more seams. This is something that a lot of new quilters don't realize. The more seams you put in, the more of a chance your block will not be as big as you want it.
There are a couple of other things that can mess up the 1/4 inch seam.... one is if you have a thicker thread and the other thing is if you are not careful when you press the block.
