I noticed that Burbank. My point was doing so many rounds on a single target made the chart too "busy" and for me it was difficult to visually separate the loads for any analysis. That is just how my brain works though, too much on a page confuses me visually. Other posters here may not have that problem and my be able to give you some worthwhile feedback
edit - just did a second look and the 180 gn Hornady load looks like it has nice node from 41.7 to 42.3. Hornady 174 from 42.3 to 43.1 seems to be a node also
