I also used to reload with the same method you use. Now with Labradar I select a series to test .2-.3 gr apart fire the string record velocity look for the flat spots and go back and try the nodes in 3 round groups usually I can find a number of nodes (3-5ish sets) not all of them shoot good groups and get eliminated on the second range trip. After the second trip I cull the remaining in spec groups by size es and deviation from that I’m usually at 1 load and then it’s down to seating depth for fine tuning and maybe annealing do help shrink es.
I find having labradar I can gather enough data to plug into quickload to get extremely accurate computer projections of my loads eliminating guess work. I feel with the extra crono data I can keep my pressures in spec and under max safely making accurate loads with low extreme spread and standard deviation. I know this set up isn’t popular with the seat of your pants or the manual is gospel reloaders but it works for me.

Good post ! That is pretty much the method I use. The manuals are a guide, QuickLoad is the verifier and a Chrono verifies Quickload. The target has the final say. Adjusting the burn rates on QL to your particular firearm is paramount to obtaining very accurate info... every time.
