For 2020, I do plan on testing the new F2 setting, which provides expanded iron bias range both up and down. I've dabbled some but need to do more. The update came out late in the year after my work location moved to the other end of the valley taking me away from a great test area I had been using. So I'll need to find a good place to work on this.
Experiment with your settings and compare them over targets. It gives you a great amount of confidence when you're hunting to trust in your settings.
