ok look at it this way, 4 years ago I went through about 7-8 hives, I found the queens and was pulling frames with young larva and eggs (plus bee's), I wanted to just raise from the eggs so they were drawn lines in the wax with my hive tool in semi-circles around the eggs so I could cut out any cells I didn't want, this was during the flow, I went in the hives 3 days later and destroyed and cells that wasn't from eggs (I only did this in one nuc, just experimenting) , out of the 10 nuc's I built taking 3 frames from each hive that hive had the best preforming queen, she was well fed and turned out the best of the rest, now a few other was good but a few nuc's kelp requeening themselves until I put a grafted queen cell in them, I tried this another time during the dearth, only 1 made it out of 7 and I didn't choose the egg section to raise from in any, you choose. reading from this site and another helped me come up with the plan because I read the same as you, really Robo and Finsky and Dwight Porter (Redtractor1) was the one's that change my mine and thats why I tried this. I am hardheaded and had to see it for myself, always do ;)
