It is very difficult to accurately measure distance without a scale let alone on the basis of a photograph, but from my
perspective, the e.d. doesn't look unacceptable or even much different than the e.d. on the other hole. Although
minimum edge distance of 2 times hole diameter is standard, (and it appears to my untrained eye that the hole meets that
requirement), minimum e.d. as measured from the center of the hole to the edge of the part is 1.5 (.147 for a #40 hole) is
often considered acceptable.
