But whats with the 40-some other holes, some are complete 0's. Not to mention the plethra of 6's and 7's..Would have been more impressed with a clean target. The resulting robinhood looks more like happenstance.
Sorry to disappoint.

However, I do not typically put up a "clean" target when I am group tuning. Those holes were probably in the target for twomonths or more.
Len,
Thank you kindly for the tip. Have you found any negatives to switching the cable orientation?
